Decoded design system

Plain's decoded design system: background #FFFFFF, text #000000, accent #F3FBE9, link #17B267, primary #1AD379; type scale h1 80px / h2 48px / body 18px; 4px spacing base; 9px base radius. The single interactive/action color is #1AD379 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Plain — Design System

> light, professional, medium, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#1AD379` |
| accent | `#F3FBE9` |
| link | `#17B267` |
| secondary | `#0A2414` |
| button_bg | `#1AD379` |
| button_text | `#0000EE` |

**Using these colors**

- **Action color** `#1AD379` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `button_bg` are all `#1AD379` — one role, not several (your action color).
- **accent** `#F3FBE9` — accent for emphasis — keep it rare on the page.
- **link** `#17B267` — inline text links, but this colour low contrast (~2.8:1 against the background), below WCAG AA - verify against the reference before using it; use the text or action color for links
- **secondary** `#0A2414` — 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): `#FFFFFF` 81.9% · `#405347` 7.6% · `#F0FBE9` 5.7% · `#CAEADA` 4.7%

## Typography

- Heading: **ABC Favorit Medium** _(free fallback: Newsreader)_
- Body: **ABC Favorit Regular** _(free fallback: Newsreader)_
- Mono: **Geist Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 400 · lh 80px · tracking -1.6px |
| h2 | 48px / 400 · lh 50px · tracking -0.96px |
| h3 | 24px / 400 · lh 28px · tracking -0.48px |
| body | 18px / 500 · lh 24px · tracking -0.18px |
| small | 15px / 400 · lh 20px · tracking -0.15px |

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

> **Fonts —** ABC Favorit Medium may be proprietary — safe free fallback: Newsreader (Google Fonts). ABC Favorit Regular may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 8px, 10px, 12px, 16px, 18px, 20px, 24px, 30px, 40px — snap all gaps/padding to these

## Radius
- base: 9px
- button: 6px
- card: 9px
- pill: 9999px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#1AD379` / `#0000EE` | none | 6px | 8px 10px 7px 10px | 400 12px | none |
| secondary | `transparent` / `#0000EE` | none | 6px | 11px 16px 11px 16px | 400 12px | none |

**States (measured, not guessed)**

- primary hover: background `#17B267`
- primary focus: outline `1px auto rgb(16, 16, 16)`

## Shadows (elevation)
- subtle: `rgba(32, 39, 44, 0.04) 0px 1.37px 2.66038px 0px`
- card: `rgba(0, 0, 0, 0.25) 0px 0px 35px 0px`

## Motion choreography (measured)
- scroll reveal: 6 elements rest at opacity 0, animate in over 300ms (6 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 584px · 928px · 960px · 1069px · 1120px · 1249px
- mobile (390px): hero 46px · body 12px · 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.
