description: A sober, editorial workflow-software interface anchored on white canvas and dark-ink type, where brand voltage comes from full-bleed signature cards in coral, dark green, peach, and dark navy that punctuate long-scroll explainer pages. Primary actions use a near-black pill CTA; secondary actions sit in a white outlined button. Type runs Haas Grotesk in modest weights — never bold for its own sake.

## Overview

Airtable's marketing surfaces are quietly editorial. The base atmosphere is white canvas, dark ink type, generous whitespace, and a near-black pill CTA — nothing is fighting for attention until a section needs to. The brand voltage doesn't come from gradient washes or accent walls; it comes from **full-bleed signature cards** in `{colors.signature-coral}`, `{colors.signature-forest}`, and `{colors.surface-dark}` that punctuate long-scroll explainer pages every two or three screens. Between those signature bands, the page reads like a print magazine: a headline, supporting copy, a small image cluster, then breathing room.

Type voice is Haas Grotesk at modest weights (400 for display, 500 for sub-titles and buttons). Display headlines never go bolder than 500 — emphasis comes from size and color contrast, not from weight. Body copy stays at 14px / 400 throughout. The pricing surface runs its own dialect: **Inter Display** at unusual mid-weights (475 / 575) and **pill-shaped buttons** (`{rounded.pill}`) that don't appear on any other page — a deliberate sub-system signaling "this page is about commercial precision."

**Key Characteristics:**
- Primary CTA is `{colors.primary}` (near-black ink) with white text and a `{rounded.lg}` (12px) corner — it reads as confident and final, never decorative.
- Secondary CTA is a `{colors.canvas}` button with `{colors.ink}` text and a hairline outline. The two together form Airtable's signature button pair.
- Hero is white canvas. There is no atmospheric gradient, no mesh, no background flourish. The brand strength comes from the type and the buttons sitting in clean whitespace.
- Brand voltage lives in **signature surface cards**: `{colors.signature-coral}`, `{colors.signature-forest}`, and `{colors.surface-dark}` carry full-bleed product callouts every few screens.
- Demo-card grids carry product UI fragments on `{colors.signature-peach}`, `{colors.signature-mint}`, `{colors.signature-cream}` and other warm pastel surfaces.
- Section rhythm: white canvas → coral signature card → white body → cream callout band → dark navy CTA → light gray CTA banner → footer. The canvas resets between every signature surface.
- Border radius is hierarchical: `{rounded.lg}` (12px) for primary CTAs and large signature cards, `{rounded.md}` (10px) for content cards and demo grids, `{rounded.sm}` (6px) for inputs, `{rounded.full}` for icon buttons. Pricing buttons jump to `{rounded.pill}` to mark themselves as a separate dialect.
- Vertical rhythm is `{spacing.section}` (96px) between major bands — universal across every page.

## Colors

### Brand & Accent
- **Primary** (`{colors.primary}` — #181d26): The dominant brand color. Used for the primary CTA background, h1/h2 display type, and the `{component.surface-dark}` band. Not "blue, then black" — black IS the primary throughout the marketing system.
- **Primary Active** (`{colors.primary-active}` — #0d1218): The press state on primary buttons.

### Surface
- **Canvas** (`{colors.canvas}` — #ffffff): The default page surface; the floor of every editorial body.
- **Surface Soft** (`{colors.surface-soft}` — #f8fafc): Tabbed feature cards and the featured pricing tier.
- **Surface Strong** (`{colors.surface-strong}` — #e0e2e6): The light gray "Start building with Airtable" CTA banner near the footer.
- **Surface Dark** (`{colors.surface-dark}` — #181d26): The dark navy CTA cards used mid-page (for example "The path to 10× every person in your organization").
- **Surface Dark Elevated** (`{colors.surface-dark-elevated}` — #1d1f25): The articles-page hero base behind the rainbow-stripe overlay.
- **Hairline** (`{colors.hairline}` — #dddddd): The 1px border tone for input outlines, table dividers, secondary-button outlines.

### Text
- **Ink** (`{colors.ink}` — #181d26): The strongest text — h1/h2 display type and primary button text-on-light. Same hex as `{colors.primary}` because they are the same role expressed at type and button layers.
- **Body** (`{colors.body}` — #333840): The default running-text color.
- **Muted** (`{colors.muted}` — #41454d): Footer links, breadcrumbs, captions.
- **Border Strong** (`{colors.border-strong}` — #9297a0): The 1px outline color on disabled secondary buttons.
- **On Primary / On Dark** (`{colors.on-primary}` — #ffffff): The text color on primary buttons and dark surfaces.

### Signature Card Surfaces
These are the colors that carry Airtable's brand voltage. They appear as full-bleed, full-card surfaces — never as accents on a small element.
- **Coral** (`{colors.signature-coral}` — #aa2d00): The largest signature card on the homepage ("Production apps in prototype speed"). Full-bleed dark coral with white type.
- **Forest** (`{colors.signature-forest}` — #0a2e0e): A deep-green signature card used in the homepage demo-grid cluster.
- **Cream** (`{colors.signature-cream}` — #f5e9d4): The cream callout band ("The path to 10× every person in your organization") — a soft beige surface holding dark type and product UI fragments.
- **Peach** (`{colors.signature-peach}` — #fcab79), **Mint** (`{colors.signature-mint}` — #a8d8c4), **Yellow** (`{colors.signature-yellow}` — #f4d35e), **Mustard** (`{colors.signature-mustard}` — #d9a441): Demo-card surfaces that carry small product UI fragments inside the multi-card grid sections.

### Semantic
- **Link** (`{colors.link}` — #1b61c9): Inline body links and anchor text. Darker on press to `{colors.link-active}` (#1a3866). Despite the `--theme_button-background-primary` CSS-variable name, this color is **not** the primary button color — it is the link color.
- **Info** (`{colors.info}` — #254fad) and **Info Border** (`{colors.info-border}` — #458fff): Inline info badges and focused-input outline.
- **Success** (`{colors.success}` — #006400) and **Success Border** (`{colors.success-border}` — #39bf45): Confirmation states.

## Typography

### Font Family
The system runs **Haas / Haas Groot Disp** (Airtable's licensed display + text type). Haas Groot Disp covers display sizes (h1 / h2); Haas Grotesk covers everything 24px and below. The fallback stack walks `-apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif`.

The pricing surface runs a separate **Inter Display** stack at mid-weights (475 / 575) — a deliberate sub-system signaling commercial precision.

### Hierarchy

| Token | Size | Weight | Line Height | Letter Spacing | Use |
|---|---|---|---|---|---|
| `{typography.display-xl}` | 48px | 500 | 1.1 | 0 | Articles page h2 — second-tier editorial headline |
| `{typography.display-lg}` | 40px | 400 | 1.2 | 0 | Homepage h1 hero |
| `{typography.display-md}` | 32px | 400 | 1.2 | 0 | Platform-page h2 — feature-section headlines |
| `{typography.title-lg}` | 24px | 400 | 1.35 | 0.12px | Section titles |
| `{typography.title-md}` | 20px | 400 | 1.5 | 0 | Sub-section titles in tabbed feature cards |
| `{typography.title-sm}` | 18px | 500 | 1.4 | 0 | Article-card titles |
| `{typography.label-md}` | 16px | 500 | 1.4 | 0 | Demo-card titles, list labels |
| `{typography.button}` | 16px | 500 | 1.4 | 0 | Standard CTA button labels |
| `{typography.body-md}` | 14px | 400 | 1.25 | 0 | Body copy, footer links, top-nav items |
| `{typography.caption}` | 14px | 500 | 1.35 | 0.16px | Light captions and meta text |
| `{typography.legal}` | 13.12px | 600 | 1.2 | 0 | Cookie/legal CTA buttons |
| `{typography.pricing-display}` | 44.8px | 475 | 1.1 | 0 | Pricing-page h1 |
| `{typography.pricing-section}` | 28px | 475 | 1.2 | 0 | Pricing-page section heads |
| `{typography.pricing-card-title}` | 20px | 475 | 1.3 | 0 | Pricing tier card plan name |

### Principles
The Haas system prefers weight 400 for display sizes — a 40px h1 is **not** bold. Visual emphasis is delegated to size, color contrast, and the signature surface cards. Where the system does want weight, it pivots to 500 (sub-titles, buttons, article titles), never 600 or 700 in the editorial body. The only true bold (600) lives in `{typography.legal}` — a sign that boldness is reserved for terms-of-service surfaces, not marketing.

The pricing-page sub-system uses Inter Display at `font-weight: 475` — a custom mid-weight between regular (400) and medium (500), shipped as a variable font.

### Note on Font Substitutes
If Haas Groot Disp and Haas Grotesk are unavailable, **Inter Display** (variable) is the closest open-source substitute for both — adjust line-height down by ~5% to match Haas's tighter cap-height. For the pricing sub-system, use Inter Display directly. On macOS / iOS, **system-ui** is sufficient; on Windows, the chain falls through to Segoe UI, which is a usable but slightly cooler substitute.

## Layout

### Spacing System
- **Base unit:** 4px (all spacing snaps to 4-multiples).
- **Tokens:** `{spacing.xxs}` 4px · `{spacing.xs}` 8px · `{spacing.sm}` 12px · `{spacing.md}` 16px · `{spacing.lg}` 24px · `{spacing.xl}` 32px · `{spacing.xxl}` 48px · `{spacing.section}` 96px.
- **Section padding (vertical):** `{spacing.section}` (96px) is the universal vertical rhythm constant — every major editorial band on every page uses 96px top + 96px bottom internal padding.
- **Card internal padding:** `{spacing.xl}` (32px) for tabbed feature cards and pricing tier cards; `{spacing.xxl}` (48px) inside signature coral / forest / dark cards; `{spacing.lg}` (24px) for cream callouts and demo-grid cards.
- **Gutters:** `{spacing.lg}` (24px) between cards in 3-up grids; `{spacing.md}` (16px) inside denser logo strips and footer column gutters.

### Grid & Container
- **Max content width:** ~1280px centered, with `{spacing.xxl}` (48px) horizontal breathing room.
- **Editorial body:** Single 8/12-column at large breakpoints, collapsing to single-column on mobile.
- **Demo-card grids:** 3 or 4 columns at desktop, 2 at tablet, 1 at mobile. Card sizes are deliberately uneven within the grid to dodge a uniform "spec sheet" feel.
- **Logo strip:** 6 monochrome partner logos in a single row at desktop; wraps to 3-up on mobile.

### Whitespace Philosophy
Airtable uses whitespace as the dominant atmospheric tool. Hero sections sit in 96px+ of pure whitespace above and below the headline + sub-headline pair, with no decoration in that whitespace. The hero is intentionally calm — there is no gradient, no aurora, no atmospheric mesh behind the type. The system trusts whitespace alone to do the framing.

## Elevation & Depth

| Level | Treatment | Use |
|---|---|---|
| Flat | No shadow, no border | Body sections, top nav, footer |
| Soft hairline | 1px `{colors.hairline}` border | Inputs, sub-nav rails, comparison-table dividers, secondary buttons |
| Button rest | Soft drop with subtle blue-tinted glow at low alpha | Primary CTA buttons (the blue tint is a holdover from the link color and reads as a faint accent under the dark button) |
| Button focus | Outer 2px blue ring at higher alpha | Keyboard focus state on primary buttons |
| Card flat | No shadow; relies on color contrast against the surface band | Signature coral / forest / dark cards, cream callouts, demo-grid cards |

The elevation philosophy is **color-block first, shadow second**. Shadows are minimal; depth is delegated to the contrast between white canvas and signature surface cards. There is no soft-glow / atmospheric-shadow / heavy-elevation language anywhere in the marketing system.

### Decorative Depth
- **Vertical rainbow stripes** appear on the articles hero only — multi-color vertical bands sitting on `{colors.surface-dark-elevated}`. This is a single-page treatment, not a system-wide signature.
- **Photography-as-depth** in the demo-card grid: every card carries a real product UI screenshot or mockup, contributing depth through legible artifact density rather than decorative effects.

## Shapes

### Border Radius Scale

| Token | Value | Use |
|---|---|---|
| `{rounded.xs}` | 2px | Cookie-consent and legal CTA buttons — system-required surfaces |
| `{rounded.sm}` | 6px | Text inputs, small inline buttons |
| `{rounded.md}` | 10px | Secondary content cards, article cards, cream callouts |
| `{rounded.lg}` | 12px | Primary CTA buttons, signature surface cards, tabbed feature cards |
| `{rounded.pill}` | 9999px | Pricing-page CTA buttons (sub-system only) |
| `{rounded.full}` | 9999px / 50% | Circular icon buttons, avatar surfaces |

### Photography Geometry
Product UI screenshots inside demo-card grids retain native aspect ratios (typically 4:3 or 16:10) and crop into `{rounded.md}` containers. Hero illustrations bleed full-width with no rounding. Article-card thumbnails use 16:9 with `{rounded.md}` corners. Avatars in testimonials use `{rounded.full}` (perfect circles). Pricing comparison table images stay rectangular with no rounding.

## Components

> **No hover states documented.** Per the global no-hover policy (Step 6), every component spec below documents only Default and Active/Pressed states. Variants live as separate entries in the `components:` front matter.

**`top-nav`** — A 64px-tall white bar pinned to the top of every page. Airtable wordmark sits at left; primary horizontal menu (Platform, Solutions, Resources, Enterprise, Pricing) sits center-left in `{typography.body-md}`; the right cluster carries a "Book Demo" outline link, "Sign up for free" `{component.button-primary}`, and "Log In" text link. The nav stays light on every page — Airtable does not invert the nav over dark sections.

### Buttons

**`button-primary`** — The signature primary CTA. Background `{colors.primary}` (near-black), text `{colors.on-primary}`, type `{typography.button}`, padding 16px × 24px, rounded `{rounded.lg}` (12px). This is the "Get started for free" / "Sign up for free" button visible on every hero. It reads as confident and final — not decorative — which is why the system uses it sparingly (one per viewport).
- Active state: `button-primary-active` darkens to `{colors.primary-active}` (#0d1218).

**`button-secondary`** — White outline button (e.g. "Book demo"). Background `{colors.canvas}`, text `{colors.ink}`, type `{typography.button}`, rounded `{rounded.lg}` (12px), 1px hairline outline. Sits next to `{component.button-primary}` as the "less-committed" choice.

**`button-secondary-on-dark`** — Same shape as `{component.button-secondary}` but used on signature coral / forest / dark surfaces. Background `{colors.canvas}`, text `{colors.ink}` — the white button stays white over dark surfaces because the system never inverts to a translucent on-dark style on the marketing site.

**`button-pricing-pill`** — The pricing-page CTA family. Background `{colors.canvas}`, text `{colors.pricing-ink}`, rounded `{rounded.pill}` (9999px), padding 12px × 24px. The only place pill-shape appears in the marketing system. Treat it as part of the pricing sub-system signaling.

**`button-legal`** — Cookie-consent and legal-banner CTAs. Background `{colors.link}`, text `{colors.on-primary}`, type `{typography.legal}` (13.12px / 600), rounded `{rounded.xs}` (2px), padding 12px × 10px. The 2px corner radius and 600 weight signal "this is a required system surface," not a designed brand surface.

**`button-icon-circular`** — 40px × 40px circular button with `{colors.canvas}` background, hairline border, and `{colors.ink}` icon. Used for carousel controls, "share", and "back" affordances.

**`text-link`** — Inline body links in `{colors.link}` (#1b61c9, the actual link blue). No underline by default. Type inherits `{typography.body-md}`.

### Cards & Containers

**`hero-band`** — The full-page-width white-canvas hero. No surface card, no border, no shadow, no atmospheric gradient — just the headline, sub-headline, and primary + secondary button pair sitting in 96px of whitespace. Vertical padding `{spacing.section}` (96px).

**`signature-coral-card`** — The large full-bleed coral card on the homepage ("Production apps in prototype speed"). Background `{colors.signature-coral}` (#aa2d00, a dark coral / oxide red), text `{colors.on-primary}`, rounded `{rounded.lg}` (12px), internal padding `{spacing.xxl}` (48px). Carries an h2 in `{typography.display-md}`, supporting copy in `{typography.body-md}`, and `{component.button-secondary-on-dark}` as the CTA.

**`signature-forest-card`** — A deep green signature card (`{colors.signature-forest}` — #0a2e0e) used as a demo-grid sibling to the coral card on the homepage.

**`hero-card-dark`** — The dark navy mid-page CTA card (e.g. "The path to 10× every person in your organization"). Background `{colors.surface-dark}` (#181d26), text `{colors.on-dark}`, rounded `{rounded.lg}` (12px), internal padding `{spacing.xxl}` (48px). The same color as `{colors.primary}` because the system uses ink as both type color and signature dark surface.

**`feature-card-tabbed`** — Light-cream cards (e.g. the "Coke / Pelosi / Conde Nast / Time Inc" tabbed feature card on the homepage). Background `{colors.surface-soft}`, rounded `{rounded.lg}` (12px), internal padding `{spacing.xl}` (32px). Left rail carries vertically-stacked tab labels in `{typography.title-md}`; right pane shows the active tab's content (illustration + body copy + small CTA).

**`cream-callout-card`** — Beige callout cards (`{colors.signature-cream}`). Rounded `{rounded.md}` (10px), internal padding `{spacing.lg}` (24px). Carry product UI fragments or stat callouts — softer than the dark/coral signature cards but still a deliberate brand surface.

**`demo-grid-card`** — Used in multi-card grids that punctuate every page. Background `{colors.canvas}` or one of the demo-grid surfaces (`{colors.signature-peach}`, `{colors.signature-mint}`, `{colors.signature-yellow}`, `{colors.signature-mustard}`), rounded `{rounded.md}` (10px), internal padding `{spacing.md}` (16px). Each card frames a product UI fragment. Card heights vary deliberately to dodge a uniform "spec sheet" feel.

**`logo-strip`** — Horizontal monochrome partner-logo row (HBO, Netflix, Amazon, Time, Conde Nast). Logos render in `{colors.muted}`, surface is `{colors.canvas}`, vertical padding `{spacing.xl}` (32px). 6 logos at desktop, 3 at mobile.

**`article-card`** — The trending-stories grid on the articles page. Background `{colors.canvas}`, rounded `{rounded.md}` (10px), internal padding `{spacing.md}` (16px). Each card carries a colorful illustrated thumbnail (16:9), a small uppercase category tag, an `{typography.title-sm}` title, and a meta line. 3-up at desktop.

**`topic-filter-rail`** — The left rail on the articles page. 240px wide, `{colors.canvas}` background, `{typography.body-md}`, vertically grouped category headings ("Marketing", "Product", "Project management", "Operations") with sub-bullets. Active item carries a small numeric count badge.

### Inputs & Forms

**`text-input`** — Standard text input. Background `{colors.canvas}`, text `{colors.ink}`, type `{typography.body-md}`, rounded `{rounded.sm}` (6px), padding 12px × 16px, height 44px. 1px hairline border in `{colors.hairline}`.

**`text-input-focus`** — Focus state. Border thickens or recolors to `{colors.info-border}`.

### Pricing Sub-System

**`pricing-tier-card`** — Standard tier card. Background `{colors.canvas}`, text `{colors.pricing-ink}`, type `{typography.pricing-card-title}` for the plan name, rounded `{rounded.md}` (10px), internal padding `{spacing.xl}` (32px). Carries the plan name, a price block in `{typography.pricing-display}` (44.8px / 475), feature checklist, and a `{component.button-pricing-pill}` at the bottom.

**`pricing-tier-card-featured`** — The featured tier (typically "Team" or "Business"). Background shifts to `{colors.surface-soft}`. No accent border, no badge — the background tone shift is the only signal.

**`pricing-comparison-row`** — Each row of the long comparison table at the bottom of the pricing page. Labels in the left column; checkmarks or values across 4 plan columns. 12px vertical padding per row, hairline divider between rows.

### Navigation Variants

**`footer`** — Light surface (`{colors.canvas}`), 6-column link list at desktop covering Platform / Solutions / Resources / Learn / Company sub-trees. Vertical padding `{spacing.section}` divided across upper link block and lower legal row. Type `{typography.body-md}`.

**`cta-band-light`** — The light gray "Start building with Airtable" CTA strip near the footer. Background `{colors.surface-strong}` (#e0e2e6), text `{colors.ink}`, rounded `{rounded.lg}` (12px), padding `{spacing.xxl}` (48px). Carries an h2 in `{typography.display-md}` and a `{component.button-primary}`.

### Signature Components

**Articles Vertical Rainbow Stripe Hero** — The articles-page hero treatment. Multi-color vertical bands at varying widths sitting on `{colors.surface-dark-elevated}`. The h1 + sub-head + CTA cluster sits center-left on top of the stripes. This is a single-page hero treatment, not a system-wide signature — do not promote it to a multi-page pattern.

## Do's and Don'ts

### Do
- Keep `{component.button-primary}` near-black. The brand's primary CTA is `{colors.primary}`, not the link blue. Mixing them up turns a confident hero into a confused one.
- Reserve `{component.button-primary}` for one primary action per viewport. The system is designed for scarcity at the brand-action layer.
- Use `{component.button-secondary}` (white with hairline outline) as the natural pair with `{component.button-primary}`. The two together form Airtable's signature button row.
- Trust whitespace as the hero atmosphere. Hero bands are intentionally calm — no gradient, no mesh, no atmospheric backdrop. Going against this reads as off-brand.
- Use `{component.signature-coral-card}`, `{component.signature-forest-card}`, and `{component.hero-card-dark}` to break editorial monotony. These are the brand's voltage moments.
- Keep `{component.demo-grid-card}` heights uneven within a grid. Uniform heights feel like a spec sheet.
- Treat the pricing surface as its own dialect: keep `{typography.pricing-display}`, `{typography.pricing-card-title}`, and `{component.button-pricing-pill}` together. Mixing them with Haas Grotesk button type breaks the sub-system's voice.
- Anchor every editorial band with `{spacing.section}` (96px) vertical padding.

### Don't
- Don't make `{colors.link}` (#1b61c9) the primary button color. It is the link color. The primary button is `{colors.primary}` (#181d26, near-black). Treating link-blue as the brand action is the most common mistake when reading Airtable's CSS variables.
- Don't add a gradient backdrop to the hero. Airtable's hero is white, full stop. Mesh, aurora, spotlight gradients all read as "another SaaS template" — not Airtable.
- Don't bold display-weight type. `{typography.display-xl}` and `{typography.display-lg}` are intentionally weight 400 / 500 — going to 700 reads as marketing-page-template.
- Don't use `{rounded.pill}` outside the pricing surface. It's a sub-system signal, not a general radius option.
- Don't repeat the same surface mode in two consecutive bands. The editorial pacing depends on rhythm: white → signature card → white → cream → dark → white. Two whites in a row read as a typography blog.
- Don't add hover state styling beyond what the system already encodes. The system documents Default and Active/Pressed only.
- Don't introduce additional accent colors beyond the documented signature card palette. The system's voltage already uses coral, forest, dark navy, cream, peach, mint, yellow, and mustard.

## Responsive Behavior

### Breakpoints

| Name | Width | Key Changes |
|---|---|---|
| Mobile | < 768px | Single-column body; top nav collapses to hamburger; demo-grid drops to 1-up; signature cards stay full-bleed; logo strip wraps to 2 rows; footer collapses to single-column |
| Tablet | 768–1024px | 2-up demo-grid; top nav stays horizontal but tightens; cream-callout cards stack 2-up; pricing comparison table becomes horizontally scrollable |
| Desktop | 1024–1440px | 3-up demo-grid (and 4-up for tighter content); full top-nav with all menu items visible; pricing tier cards render 4-across |
| Wide | > 1440px | Same as Desktop with more outer breathing room; max content width caps at ~1280px and the page adds outer margin rather than scaling type up |

### Touch Targets
- `{component.button-primary}` and siblings render at 48 × 48px minimum (16px vertical padding + 16px line-height) — comfortably above WCAG AAA's 44 × 44.
- `{component.button-icon-circular}` is exactly 40 × 40px — slightly under WCAG's recommended 44, but the centered icon and dot-radius compensate visually.
- `{component.text-input}` height is 44px.

### Collapsing Strategy
- Top nav collapses to a hamburger at < 768px; the menu opens as a full-screen sheet rather than a dropdown.
- Card grids reduce columns rather than scaling cards down.
- The `{component.feature-card-tabbed}` re-stacks the tab rail above the content pane on mobile.
- The pricing comparison table converts to horizontally-scrollable swipe at < 1024px; the four plan headers stay visible while body rows scroll.

### Image Behavior
- Demo-card UI screenshots crop to fit their container rather than scaling up.
- Hero illustrations bleed full-width on mobile, losing horizontal margin.
- Signature card images (inside coral / forest / dark cards) compress to their card width without cropping.

## Iteration Guide

1. Focus on ONE component at a time. Reference its YAML key directly (`{component.button-primary}`, `{component.signature-coral-card}`).
2. When adding a new component, decide first which sub-system it belongs to: the main editorial system (Haas, `{rounded.lg}`/`{rounded.md}`) or the pricing sub-system (Inter Display, `{rounded.pill}`).
3. Variants of an existing component (`-active`, `-disabled`, `-focus`) live as separate entries in `components:` — never as nested state objects.
4. Use `{token.refs}` everywhere prose mentions a color, a radius, a typography role, or a spacing value. Hex codes appear at most once next to the reference.
5. Never document hover. The system documents Default and Active/Pressed states only.
6. Run `npx @google/design.md lint DESIGN.md` after edits — `broken-ref`, `contrast-ratio`, and `orphaned-tokens` warnings flag issues automatically.
7. When in doubt about emphasis: bigger type before bolder type, signature surface card before solid accent.

## Known Gaps

- The exact hex values of pastel demo-grid surfaces (`{colors.signature-peach}`, `{colors.signature-mint}`, `{colors.signature-yellow}`, `{colors.signature-mustard}`) are inferred from screenshot pixel sampling. Some product launches may swap these surfaces seasonally.
- Hover behavior across all components is not documented (per global no-hover policy).
- Animation and transition timings are not in scope.
- Form validation states beyond `text-input-focus` are not extracted — error and success states for inputs would need a dedicated form page to confirm.
- The pricing comparison table's checkmark glyph and column-divider widths are described structurally but not formalized as tokens.
- The CSS variable `--theme_button-background-primary: #1b61c9` exists at `:root` but is not used as the primary CTA color anywhere on the marketing site. It maps to the link/info color role instead. Documented here so future extractions don't re-trip over the misleading variable name.
