Decoded design system

Sourcegraph's decoded design system: background #0E0D0D, text #ECECEE, accent #F34E3F, link #111111, primary #9E9EFF; type scale h1 80px / h2 72px / body 16px; 4px spacing base; 8px base radius. The single interactive/action color is #F8F8F8 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F8F8F8 — the single interactive color; only on things you click or must notice, never large fills.
• accent #F34E3F — accent for emphasis — keep it rare on the page.
• primary #9E9EFF — a brand color — but the call-to-action uses #F8F8F8, not this.
• link #111111 — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #410604 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

## Colors

| Role | Value |
|------|-------|
| bg | `#0E0D0D` |
| surface | `#1B1A1A` |
| border | `#2F2E2E` |

**Using these colors**

- **Action color** `#F8F8F8` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#F34E3F` — accent for emphasis — keep it rare on the page.
- **primary** `#9E9EFF` — a brand color — but the call-to-action uses #F8F8F8, not this.
- **link** `#111111` — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#410604` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#020202` 88.2% · `#7B7574` 7.5% · `#310201` 4.3%

## Typography

- Heading: **Poly Sans** _(free fallback: Newsreader)_
- Body: **Poly Sans** _(free fallback: Newsreader)_
- Mono: **Poly Sans Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 500 · lh 77px · tracking -2.48px |
| h2 | 72px / 500 · lh 50px · tracking -2.23px |
| h3 | 56px / 500 · lh 60px · tracking -0.5px |
| body | 16px / 400 · lh 20px |
| small | 15px / 400 · lh 23px · tracking 0.26px |

- Weight ladder: 300 · 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Poly Sans may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 3px, 4px, 6px, 8px, 10px, 12px, 14px, 16px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 56px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 4px
- card: 8px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F8F8F8` / `#020202` | 1px solid rgb(255, 255, 255) | 4px | 8px 12px 8px 12px | 700 16px | none |
| secondary | `#222222` / `#DEDEDE` | 1px solid oklch(0.35 0 0) | 6px | 6.4px 14.4px 6.4px 14.4px | 600 13px / 0.256px | none |

**States (measured, not guessed)**

- primary hover: background `#E4E4E4`
- primary focus: background `#E4E4E4` · outline `3px solid rgba(0, 65, 198, 0.8)`
- secondary hover: background `#2E2E2E`
- transition: `background-color 0.2s ease-out`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.06) 0px 1px 2px 0px, rgba(0, 0, 0, 0.06) 0px 4px 8px 0px, rgba(0, 0, 0, 0.08) 0px 12px 24px 0px`
- card: `rgba(0, 0, 0, 0.08) 0px 4px 24px 0px, rgba(0, 0, 0, 0.05) 0px 1px 4px 0px`
- overlay: `rgba(0, 0, 0, 0.5) 0px 12px 40px 0px`

## Motion
- durations: 150ms (dominant) · 500ms · 300ms
- easings: `ease` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: color, opacity, transform, stroke-dashoffset

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
