Decoded design system

Endel's decoded design system: background #000000, text #FFFFFF, accent #262626, link #FFFFFF, primary #FFFFFF; type scale h1 60px / h2 44px / body 22px; 8px spacing base; 12px base radius. The single interactive/action color is #262626 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #262626 — the single interactive color; only on things you click or must notice, never large fills.
• primary, link are all #FFFFFF — one role, not several (the action color).
• accent, button_bg are all #262626 — one role, not several (the action color).
• accent #262626 — 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.

# Endel — Design System

> dark, modern, medium, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#0F0F0F` |
| border | `#262626` |
| text | `#FFFFFF` |
| text_muted | `#9E9E9E` |
| primary | `#FFFFFF` |
| accent | `#262626` |
| link | `#FFFFFF` |
| button_bg | `#262626` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#262626` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `link` are all `#FFFFFF` — one role, not several.
- `accent`, `button_bg` are all `#262626` — one role, not several (your action color).
- **accent** `#262626` — 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.
- **Page coverage** (full-page screenshot pixels): `#000000` 76.3% · `#272727` 10.3% · `#0E0E0E` 8.5% · `#5B5B5B` 4.9%

## Typography

- Heading: **Apercu Pro** _(free fallback: Newsreader)_
- Body: **Apercu Pro** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 60px / 400 · lh 72px · tracking 0.35px |
| h2 | 44px / 400 · lh 56px |
| body | 22px / 400 · lh 28px |
| small | 18px / 400 · lh 24px |

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

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 12px, 16px, 20px, 24px, 32px, 40px, 64px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 12px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#262626` / `#FFFFFF` | 2px solid rgba(0, 0, 0, 0) | 12px | 0px 12px 0px 12px | 400 16px | rgb(255, 255, 255) 0px 0px 15px 0px |
| secondary | `#262626` / `#FFFFFF` | 2px solid rgb(38, 38, 38) | 12px | 0px 12px 0px 12px | 400 16px | none |

**States (measured, not guessed)**

- primary hover: border `2px solid rgb(128, 128, 128)` · background `#808080`
- primary focus: box-shadow `rgb(102, 102, 102) 0px 0px 0px 6px`
- secondary hover: border `2px solid rgb(128, 128, 128)` · background `#808080`
- transition: `background-color 0.2s ease`

## Shadows (elevation)
- card: `rgb(255, 255, 255) 0px 0px 15px 0px`
- button: `rgb(255, 255, 255) 0px 0px 15px 0px`

## Motion
- durations: 200ms (dominant) · 300ms
- easings: `ease` (dominant)
- animated properties: background-color, border-color, transform

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

## 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.
