Tokens

Coder's decoded design system: background #FFFFFF, text #0A0C0C, accent #0A0C0C, link #A19CC8, primary #FF8067; type scale h1 68px / h2 14px / body 18px; 4px spacing base; 0px base radius. The single interactive/action color is #0A0C0C — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F0F0F0`
border	`#DADADA`
text	`#0A0C0C`
text_muted	`#676868`
primary	`#FF8067`
accent	`#0A0C0C`
link	`#A19CC8`
secondary	`#9EDFE9`
button_bg	`#0A0C0C`
button_text	`#FFFFFF`

Using these colors

Action color #0A0C0C — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #0A0C0C — one role, not several (the action color).
accent #0A0C0C — 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 #FF8067 — a brand color — but the call-to-action uses #0A0C0C, not this.
link #A19CC8 — fails contrast on the background (~2.6:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
secondary #9EDFE9 — 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 | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DADADA` |
| text | `#0A0C0C` |
| text_muted | `#676868` |
| primary | `#FF8067` |
| accent | `#0A0C0C` |
| link | `#A19CC8` |
| secondary | `#9EDFE9` |
| button_bg | `#0A0C0C` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#0A0C0C` — 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 `#0A0C0C` — one role, not several (your action color).
- **accent** `#0A0C0C` — 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** `#FF8067` — a brand color — but the call-to-action uses #0A0C0C, not this.
- **link** `#A19CC8` — fails contrast on the background (~2.6:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#9EDFE9` — 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): `#D8C2EE` 52.8% · `#FFFFFF` 18.5% · `#4D4C4D` 12.6% · `#E6E3F8` 7.4%

## Typography

- Heading: **Geist**
- Body: **LayGrotesk** _(free fallback: Newsreader)_
- Mono: **FT System Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 68px / 500 · lh 71px · tracking -0.68px |
| h2 | 56px / 500 · lh 56px · tracking -0.56px |
| h3 | 52px / 500 · lh 55px · tracking -0.52px |
| body | 20px / 400 · lh 28px · tracking 0.4px |
| small | 18px / 400 · lh 25px · tracking 0.36px |

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

> **Fonts —** Geist — free, on Google. LayGrotesk may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 7px, 8px, 10px, 11px, 12px, 14px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 164px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 9999px
- card: 4px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `oklch(0.97 0 0)` / `oklch(0.15 0.0034 196.79)` | none | 3.35544e+07px | 14px 20px 14px 20px | 500 14px / 0.14px | none |
| secondary | `#F2EDFF` / `#000000` | 1px solid rgb(0, 0, 0) | 3.5px | 7px 10.5px 7px 10.5px | 700 14px | none |

**States (measured, not guessed)**

- primary hover: background `oklab(0.946192 0 0)`
- primary focus: outline `1px auto oklab(0.705 0.00415142 -0.0144141 / 0.5)`
- secondary hover: background `#DED9EB`
- transition: `scale 0.4s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.1) 0px 2px 10px 0px`

## Motion
- durations: 300ms (dominant) · 400ms · 200ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- animated properties: scale, background-color, transform, translate

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

- scroll reveal: 2 elements rest at opacity 0, animate in over 0.3s cubic-bezier(0.4, 0, 0.2, 1) (2 revealed during the drive).

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

## 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.
