Decoded design system

Dia's decoded design system: background #F8F8F8, text #252525, accent #000000, link #9CA3AF, primary #5863EA; type scale h1 48px / h2 24px / body 18px; 4px spacing base; 20px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #000000 — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #000000 — one role, not several (the action color).
• accent #000000 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• primary #5863EA — a brand color — but the call-to-action uses #000000, not this.
• link #9CA3AF — fails contrast on the background (~2.4:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).

## Colors

| Role | Value |
|------|-------|
| bg | `#F8F8F8` |
| surface | `#EBEBEB` |
| border | `#D8D8D8` |
| text | `#252525` |
| text_muted | `#757575` |

| link | `#9CA3AF` |
| button_bg | `#000000` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#000000` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#000000` — one role, not several (your action color).
- **accent** `#000000` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#5863EA` — a brand color — but the call-to-action uses #000000, not this.
- **link** `#9CA3AF` — fails contrast on the background (~2.4:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **Page coverage** (full-page screenshot pixels): `#020204` 86.8% · `#99867B` 13.2%

## Typography

- Heading: **ABC Oracle Triple** _(free fallback: Newsreader)_
- Body: **ABC Oracle** _(free fallback: Newsreader)_
- Mono: **ABC Favorit Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 48px / 650 · lh 56px · tracking -2.4px |
| h2 | 24px / 650 · lh 30px · tracking -0.72px |
| h3 | 22px / 400 · lh 30px |
| body | 18px / 400 · lh 27px · tracking -0.36px |
| small | 16px / 400 · lh 20px |

- Weight ladder: 400 · 500 · 650 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 5px, 10px, 14px, 16px, 20px, 24px, 28px, 30px, 40px, 70px — snap all gaps/padding to these

## Radius
- base: 20px
- button: 9999px
- card: 12px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0.65)` / `#FFFFFF` | none | 9999px | 10px 20px 10px 12px | 500 16px | rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.6) 0px 8px 30px -8px |
| secondary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | none | 14px | 0px 0px 0px 0px | 400 10px | none |

**States (measured, not guessed)**

- primary hover: background `rgba(0, 0, 0, 0.8)`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `background-color 0.2s cubic-bezier(0, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.06) 0px 2px 8px 0px, rgba(0, 0, 0, 0.04) 0px 0px 2px 0px`
- card: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.6) 0px 8px 30px -8px`
- button: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.6) 0px 8px 30px -8px`

## Motion
- durations: 200ms (dominant) · 300ms · 250ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0, 0, 0.2, 1)`
- animated properties: background-color, border-color, text-decoration-color, color

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

## Layout (measured)
- container max 1180px · common grid: 12-col
- nav: 52px fixed

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 900 | — | — | 0/0 | — |
| 980 | 2176 | — | — | 0/0 | — |
| 3276 | 2056 | 12 | 20 | 0/0 | — |

## Motion choreography (measured)
- `div.pointer-events-none` — opacity 1→0 — 1000ms linear(0 0%, 0.0101 1.0101010101010102%, 0.0202 2.0202020202020203%, 0.0303 3.0303030303030303%, 0.0404 4.04040404040404
- stagger: `div` ×9 — 50ms apart
- scroll reveal: 5 elements rest at opacity 0, animate in over 400ms (5 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 600px · 800px · 900px · 1000px · 1100px · 1200px
- mobile (390px): hero 70px · body 10px · 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.
