+name: Cursor
+description: An AI-first code editor whose marketing site reads like a quietly-confident developer-tools brand with a warm-cream editorial canvas (`#f7f7f4`) instead of the typical dark IDE atmosphere. Near-black warm ink (`#26251e`) carries body and display alike — display sits at weight 400 with negative letter-spacing for a magazine feel rather than a bold tech voice. The single brand voltage is **Cursor Orange** (`#f54e00`) reserved for primary CTAs and the wordmark. A signature pastel timeline palette (peach, mint, blue, lavender, gold) marks AI-action stages (Thinking / Reading / Editing / Grepping / Done) — only inside in-product timeline visualizations. Cards use minimal hairlines, no shadows, generous 80px section rhythm. CursorGothic for display/body, JetBrains Mono on every code surface (which is roughly half the page).

+
+## Overview
+
+Cursor's marketing site reads as a quietly-confident developer brand that believes in editorial calm over IDE-darkness. The base canvas is **warm cream** (`{colors.canvas}` — #f7f7f4) holding warm near-black ink (`{colors.ink}` — #26251e) for body and display alike. The single brand voltage is **Cursor Orange** (`{colors.primary}` — #f54e00) reserved for primary CTAs and the wordmark — used scarcely.
+
+Type runs **CursorGothic** as the single sans family. Display sits at weight 400 with negative letter-spacing — a magazine-editorial voice rather than tech-bombastic. JetBrains Mono carries every code surface (and code surfaces are roughly half the page).
+
+The brand's strongest visual signature is the **AI-timeline pill palette**: five pastel pills (peach `{colors.timeline-thinking}`, mint `{colors.timeline-grep}`, blue `{colors.timeline-read}`, lavender `{colors.timeline-edit}`, gold `{colors.timeline-done}`) marking AI-action stages inside in-product timeline visualizations. Used only in product UI — never as system action colors.
+
+**Key Characteristics:**
+- Warm cream canvas, not white. Ink is warm (#26251e), not pure black.
+- Single CTA color: `{colors.primary}` (Cursor Orange #f54e00). Used scarcely.
+- Display weight stays at 400 — never bold. Magazine voice.
+- AI timeline pastels: 5 dedicated tokens for in-product agent action stages.
+- Compact 8px CTA radius — developer dialect.
+- Hairline-only depth; no drop shadows.
+- 80px section rhythm.
+
+## Colors
+
+### Brand & Accent

+**CursorGothic** is the licensed display + body family. Fallback: `system-ui, "Helvetica Neue", Helvetica, Arial, sans-serif`. Code surfaces switch to **JetBrains Mono**.
+
+### Hierarchy
+
+| Token | Size | Weight | Line Height | Letter Spacing | Use |
+|---|---|---|---|---|---|
+| `{typography.display-mega}` | 72px | 400 | 1.1 | -2.16px | Homepage hero h1 |
+| `{typography.display-lg}` | 36px | 400 | 1.2 | -0.72px | Section heads |
+| `{typography.display-md}` | 26px | 400 | 1.25 | -0.325px | Sub-section heads |
+| `{typography.display-sm}` | 22px | 400 | 1.3 | -0.11px | Card group titles |
+| `{typography.title-md}` | 18px | 600 | 1.4 | 0 | Component titles |
+| `{typography.title-sm}` | 16px | 600 | 1.4 | 0 | List labels |
+| `{typography.body-md}` | 16px | 400 | 1.5 | 0 | Default body |
+| `{typography.body-tracked}` | 16px | 400 | 1.5 | 0.08px | Tracked editorial body |
+| `{typography.body-sm}` | 14px | 400 | 1.5 | 0 | Footer body |
+| `{typography.caption}` | 13px | 400 | 1.4 | 0 | Photo captions |
+| `{typography.caption-uppercase}` | 11px | 600 | 1.4 | 0.88px | Section labels, timeline pill labels |
+| `{typography.code}` | 13px | 400 | 1.5 | 0 | Code blocks — JetBrains Mono |
+| `{typography.button}` | 14px | 500 | 1.0 | 0 | CTA pill labels |
+| `{typography.nav-link}` | 14px | 500 | 1.4 | 0 | Top-nav menu |
+
+### Principles
+- **Display weight stays at 400.** Magazine voice, never bold.
+- **Negative letter-spacing on display only.** -0.11px to -2.16px tracking.
+- **JetBrains Mono on every code surface.**
+
+### Note on Font Substitutes
+CursorGothic is licensed. Open-source substitute: **Inter** at weight 400 with letter-spacing -1.5%. Or **GT Sectra** for a more editorial feel.
+
+## Layout
+
+### Spacing System
+- **Base unit:** 4px.
+- **Tokens:** `{spacing.xxs}` 4px · `{spacing.xs}` 8px · `{spacing.sm}` 12px · `{spacing.base}` 16px · `{spacing.md}` 20px · `{spacing.lg}` 24px · `{spacing.xl}` 32px · `{spacing.xxl}` 48px · `{spacing.section}` 80px.
+- **Section padding:** 80px.
+
+### Grid & Container
+- Max content width: ~1200px.
+- Editorial body: 12-column grid.
+- Feature card grids: 2-up at desktop for splits, 3-up for benefits.
+- Footer: 5-column at desktop.
+
+### Whitespace Philosophy
+Generous editorial pacing — closer to a print magazine than a tech site. The cream canvas has plenty of breathing room; cards within bands sit close (16-24px gap).
+
+## Elevation & Depth
+
+The system uses **hairline-only depth**. No drop shadows, no elevation tiers. Cards float above the canvas via 1px hairlines and the slight white-on-cream contrast.
+
+| Level | Treatment | Use |
+|---|---|---|
+| Flat (canvas) | `{colors.canvas}` (#f7f7f4) | Body bands, footer |
+| Card | `{colors.surface-card}` (#ffffff) | Content cards |
+| Hairline border | 1px `{colors.hairline}` | Card outlines, dividers |
+| IDE pane | `{colors.canvas-soft}` (#fafaf7) | Inside IDE mockup cards |
+
+### Decorative Depth
+- **IDE-mockup cards** are the only "elevated" element. White card on cream canvas with internal pane structure mimicking the actual Cursor editor.
+- **Timeline pastel pills** add chromatic depth without surface elevation.
+
+## Shapes
+
+### Border Radius Scale

+| `{rounded.xs}` | 4px | Inline tags |
+| `{rounded.sm}` | 6px | Compact rows |
+| `{rounded.md}` | 8px | CTA buttons, form inputs |
+| `{rounded.lg}` | 12px | Cards, IDE panes |
+| `{rounded.xl}` | 16px | Larger feature cards (rare) |
+| `{rounded.pill}` | 9999px | Timeline pills, badges |
+| `{rounded.full}` | 9999px | Avatars (rare) |

+
+**`footer-link`** — Background transparent, text `{colors.body}`, type `{typography.body-sm}`.
+
+## Do's and Don'ts
+
+### Do
+- Reserve `{colors.primary}` (Cursor Orange) for primary CTAs and brand wordmark.
+- Keep display weight at 400. The editorial voice depends on this.
+- Use the cream `{colors.canvas}` page floor — never pure white.
+- Render every code surface (inline, blocks, IDE panes) in JetBrains Mono.
+- Use timeline pastels only inside in-product agent visualizations — never as system action colors.
+
+### Don't
+- Don't introduce a secondary brand action color. Cursor Orange is the only one.
+- Don't drop display to bold weights (700+). Magazine voice depends on 400.
+- Don't add drop shadows. Hairlines + ink-on-cream contrast carry the depth.
+- Don't use timeline pastels on non-timeline UI. They're scoped to the agent timeline only.
+- Don't extract a CTA color from a third-party widget (cookie consent, OneTrust). The brand's CTA is what appears on actual product CTAs.
+
+## Responsive Behavior
+
+### Breakpoints
+
+| Name | Width | Key Changes |
+|---|---|---|
+| Mobile | < 640px | Hero h1 72→32px; IDE mockup collapses to single pane preview; feature grid 1-up; nav hamburger. |
+| Tablet | 640–1024px | Hero h1 56px; IDE mockup compresses; feature grid 2-up. |
+| Desktop | 1024–1280px | Full hero h1 72px; full multi-pane IDE mockup; feature grid 3-up. |
+| Wide | > 1280px | Content caps at 1200px. |
+
+### Touch Targets
+- Primary CTA at 40px height — at WCAG AA, padded for AAA.
+- Download CTA at 44px — at AAA.
+
+### Collapsing Strategy
+- Top nav switches to hamburger below 768px.
+- IDE mockup multi-pane collapses to a single primary pane preview on mobile.
+- Feature grid: 3-up → 2-up → 1-up.
+
+## Iteration Guide
+
+1. Focus on a single component at a time.
+2. CTAs default to `{rounded.md}` (8px). Cards use `{rounded.lg}` (12px).
+3. Variants live as separate entries inside `components:`.
+4. Use `{token.refs}` everywhere — never inline hex.
+5. Hover state never documented.
+6. CursorGothic 400 for display, 400/500/600 for body. JetBrains Mono on every code surface.
+7. Cursor Orange stays scarce.
+8. Timeline pastels stay scoped to in-product agent visualizations.

+## Known Gaps
+
+- CursorGothic is a licensed typeface; Inter is the substitute.
+- Animation timings (timeline pill entrance, IDE pane reveal) out of scope.
+- In-app surfaces (code editor, chat panel, agent timeline) only partially captured via marketing IDE mockups.
+- Form validation states beyond focus not visible on captured surfaces.
