Decoded design system

Logical Kitten's decoded design system: background #0E0F11, text #ECEDEB, link #0E0F11, primary #0E0F11; type scale h1 95px / h2 59px / body 16px; 8px spacing base; 10px base radius. The single interactive/action color is #0E0F11 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0E0F11 — the single interactive color; only on things you click or must notice, never large fills.
• primary, link are all #0E0F11 — one role, not several (the action color).

# Logical Kitten — Design System

> dark — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#0E0F11` |
| surface | `#1B1C1E` |
| border | `#2F3031` |
| text | `#ECEDEB` |
| text_muted | `#979898` |
| primary | `#0E0F11` |
| link | `#0E0F11` |
| button_bg | `rgba(0, 0, 0, 0)` |
| button_text | `#0E0F11` |

**Using these colors**

- **Action color** `#0E0F11` — 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 `#0E0F11` — one role, not several (your action color).
- **Page coverage** (full-page screenshot pixels): `#040404` 54.6% · `#191C20` 37.5% · `#727579` 7.9%

## Typography

- Heading: **Outfit**
- Body: **Outfit**
- Mono: **IBM Plex Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 95px / 500 · lh 95px · tracking -2.85px |
| h2 | 59px / 500 · lh 62px · tracking -1.66px |
| h3 | 51px / 500 · lh 55px · tracking -1.33px |
| body | 16px / 400 · lh 25px |
| small | 15px / 400 · lh 24px |

- Weight ladder: 300 · 400 · 500 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Outfit — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 9px, 10px, 11px, 12px, 18px, 22px, 24px, 26px — snap all gaps/padding to these
- section rhythm: 110px top/bottom padding per section (measured)

## Radius
- base: 10px
- button: 10px
- card: 14px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#0E0F11` | none | 10px | 9px 18px 9px 18px | 500 14.4px | rgba(255, 255, 255, 0.9) 0px 1px 0px 0px inset, rgba(0, 0, 0, 0.18) 0px -2px 0px 0px inset, rgba(0, 0, 0, 0.4) 0px 8px 22px 0px |

**States (measured, not guessed)**

- primary focus: outline `2px solid rgb(236, 237, 235)`
- transition: `transform 0.12s ease`

## Motion
- durations: 850ms (dominant) · 1400ms · 250ms
- easings: `cubic-bezier(0.22, 1, 0.36, 1)` (dominant) · `ease`
- animated properties: transform, opacity, stroke-dashoffset, box-shadow

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

_…and 3 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1240px · common grid: 2-col
- nav: 68px fixed · backdrop blur(16px) · border-bottom 1px solid rgba(236, 237, 235, 0.043) · bg rgba(14, 15, 17, 0.78)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 900 | 2 | 58 | 110/70 | 58/42 |

## Motion choreography (measured)
Load order: `h1` @0ms → `span.live-dot` @0ms → `div.crow`×2 @17ms → `span.chip`×2 @17ms → `p.hero-sub` @60ms → `div.hero-actions` @193ms
- `h1` — opacity 0→1 · transform translateY(16px)→none — 1000ms cubic-bezier(0.22, 1, 0.36, 1)
- `div.crow` — opacity 0→1 · transform translateY(-8px)→none — 450ms cubic-bezier(0.22, 1, 0.36, 1)
- `p.hero-sub` — opacity 0→1 · transform translateY(16px)→none — 1000ms cubic-bezier(0.22, 1, 0.36, 1) (delay 140ms)
- `div.hero-actions` — opacity 0→1 · transform translateY(16px)→none — 1000ms cubic-bezier(0.22, 1, 0.36, 1) (delay 280ms)
- `div.console` — opacity 0→1 · transform translateY(18px)→none — 1000ms cubic-bezier(0.22, 1, 0.36, 1) (delay 400ms)
- `span.live-dot` — opacity 1→1 — 1600ms ease-in-out · loops
- scroll reveal: 5 elements rest at opacity 0, translateY(20px), animate in over 0.85s cubic-bezier(0.22, 1, 0.36, 1) (5 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 900px
- mobile (390px): hero 45px · body 17px · nav: hamburger

## 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.
