Decoded design system

ClickHouse's decoded design system: background #131312, text #ECECEE, accent #FAFF69, link #000000, primary #FAFF69; type scale h1 96px / h2 36px / body 16px; 4px spacing base; 8px base radius. The single interactive/action color is #166534 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #166534 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #FAFF69 — one role, not several (the action color).
• accent #FAFF69 — accent for emphasis — keep it rare on the page.
• link #000000 — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #4F5101 — 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.

# ClickHouse — Design System

> dark, professional, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#131312` |
| surface | `#20201F` |
| border | `#333333` |
| text | `#ECECEE` |
| text_muted | `#99999A` |
| primary | `#FAFF69` |
| accent | `#FAFF69` |
| link | `#000000` |
| secondary | `#4F5101` |
| button_bg | `#166534` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#166534` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent` are all `#FAFF69` — one role, not several.
- **accent** `#FAFF69` — accent for emphasis — keep it rare on the page.
- **link** `#000000` — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#4F5101` — 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): `#131312` 49.2% · `#282826` 43.1% · `#797E6F` 7.7%

## Typography

- Heading: **Inter**
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 96px / 600 · lh 96px |
| h2 | 36px / 600 · lh 45px |
| h3 | 24px / 400 · lh 36px |
| body | 16px / 400 · lh 24px |
| small | 14px / 500 · lh 18px |
| eyebrow | 14px / 600 · tracking 0.35px |

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

> **Fonts —** Inter — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 5px, 6px, 8px, 10px, 12px, 16px, 24px, 32px, 40px — snap all gaps/padding to these
- section rhythm: 96px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 0px
- card: 8px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#166534` / `#FFFFFF` | 1px solid rgb(20, 20, 20) | 0px | 12px 16px 12px 16px | 400 14px | none |
| secondary | `lab(97.5527 -15.3436 68.8452)` / `lab(6.77022 -0.00000745058 0)` | 1px solid lab(97.5527 -15.3436 68.8452) | 4px | 10px 16px 10px 16px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `#14532D`
- primary focus: outline `1px solid rgb(20, 20, 20)`
- secondary hover: border `1px solid lab(93.4022 -17.6904 90.034)` · background `lab(93.4022 -17.6904 90.034)`

## Motion
- durations: 150ms (dominant) · 300ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- animated properties: color, background-color, border-color, outline-color

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

## Motion choreography (measured)
Load order: `h1.animate-fade-up` @0ms → `div.absolute` @2ms → `p.animate-fade-up` @79ms → `div.animate-fade-up`×2 @270ms → `div.w-full` @641ms → `div.cc-window` @1536ms
- `h1.animate-fade-up` — opacity 0→1 · transform translateY(8px)→translateY(0px) — 500ms ease
- `p.animate-fade-up` — opacity 0→1 · transform translateY(8px)→translateY(0px) — 500ms ease (delay 200ms)
- `div.animate-fade-up` ×2 — opacity 0→1 · transform translateY(8px)→translateY(0px) — 500ms ease (delay 400ms)
- `div.absolute` — opacity 1→1 — 2000ms cubic-bezier(0.4, 0, 0.6, 1) · loops
- overlay dialog (auto-opened): panel #141414 · r 10px · border 1px solid rgb(57, 57, 57)

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

- mobile (390px): hero 24px · body 16px · nav: inline

## 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.
