Decoded design system

Default's decoded design system: background #0B0C0E, text #FFFFFF, accent #F2F2F2, link #FFFFFF, primary #FFFFFF; type scale h1 64px / h2 52px / body 14px; 4px spacing base; 0px base radius. The single interactive/action color is #F2F2F2 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#0B0C0E`
surface	`#191A1C`
border	`#2F3032`
text	`#FFFFFF`
text_muted	`#A2A2A3`
primary	`#FFFFFF`
accent	`#F2F2F2`
link	`#FFFFFF`
button_bg	`#F2F2F2`
button_text	`#333333`

Using these colors

Action color #F2F2F2 — 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 #F2F2F2 — one role, not several (the action color).
accent #F2F2F2 — 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.

## Colors

| Role | Value |
|------|-------|
| bg | `#0B0C0E` |
| surface | `#191A1C` |
| border | `#2F3032` |
| text | `#FFFFFF` |
| text_muted | `#A2A2A3` |

| accent | `#F2F2F2` |
| link | `#FFFFFF` |
| button_bg | `#F2F2F2` |
| button_text | `#333333` |

**Using these colors**

- **Action color** `#F2F2F2` — 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 `#F2F2F2` — one role, not several (your action color).
- **accent** `#F2F2F2` — 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): `#0B0C0E` 50.9% · `#232123` 44.2% · `#4F4E4F` 4.9%

## Typography

- Heading: **Inter**

| body | 14px / 400 · lh 22px · tracking -0.32px |
| small | 13px / 500 · lh 18px · tracking -0.2px |

- Weight ladder: 400 · 420 · 440 · 450 · 500 — 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, 3px, 4px, 5px, 6px, 7px, 8px, 9px, 10px, 11px — snap all gaps/padding to these
- section rhythm: 50px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 10px
- card: 10px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F2F2F2` / `#333333` | 1px solid rgba(255, 255, 255, 0.2) | 10px | 8px 20px 8px 20px | 500 13px / -0.2px | rgba(0, 0, 0, 0.1) 0px 1px 4px 0px, rgba(0, 0, 0, 0.1) 0px 0px 1px 0px |
| secondary | `oklab(0.999994 0.0000455678 0.0000200868 / 0.05)` / `rgba(255, 255, 255, 0.898)` | 1px solid rgba(0, 0, 0, 0) | 10px | 8px 16px 8px 16px | 500 14px / -0.32px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `oklab(0.999994 0.0000455678 0.0000200868 / 0.08)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.1) 0px 1px 4px 0px, rgba(0, 0, 0, 0.1) 0px 0px 1px 0px`
- card: `rgba(0, 0, 0, 0.063) 0px 4px 6px 1px, rgba(0, 0, 0, 0.15) 0px 0px 1px 1px`
- button: `rgba(0, 0, 0, 0.1) 0px 1px 4px 0px, rgba(0, 0, 0, 0.1) 0px 0px 1px 0px`
- overlay: `rgba(0, 0, 0, 0.05) 0px 100px 106px 0px, rgba(0, 0, 0, 0.04) 0px 42px 44px 0px, rgba(0, 0, 0, 0.03) 0px 22px 24px 0px, rgba(0, 0, 0, 0.03) 0px 12px 12px 0px`

## Motion
- durations: 150ms (dominant) · 320ms · 130ms
- easings: `ease-out` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: opacity, transform, translate, scale

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

- overlay dropdown (auto-opened): panel #0B0C0E · r 16px · border 1px solid rgba(255, 255, 255, 0.14) · shadow 

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.
