Decoded design system

Lumiui's decoded design system: background #FFFFFF, text #080E19, accent #5D9EFF, link #080E19, primary #DAE6FF; type scale h1 72px / h2 72px / body 18px; 8px spacing base; 6px base radius. The single interactive/action color is #5D9EFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #5D9EFF — the single interactive color; only on things you click or must notice, never large fills.
• accent, secondary, button_bg are all #5D9EFF — one role, not several (the action color).
• accent #5D9EFF — 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 #DAE6FF — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #5D9EFF).
• link #080E19 — inline text links and link-styled controls.

# Lumiui — Design System

> light, modern, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F1` |
| border | `#D9DADC` |
| text | `#080E19` |
| text_muted | `#656970` |
| primary | `#DAE6FF` |
| accent | `#5D9EFF` |
| link | `#080E19` |
| secondary | `#5D9EFF` |
| button_bg | `#5D9EFF` |
| button_text | `#002045` |

**Using these colors**

- **Action color** `#5D9EFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `secondary`, `button_bg` are all `#5D9EFF` — one role, not several (your action color).
- **accent** `#5D9EFF` — 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** `#DAE6FF` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #5D9EFF).
- **link** `#080E19` — inline text links and link-styled controls.
- **Page coverage** (full-page screenshot pixels): `#080E19` 80.6% · `#131C29` 14.3% · `#46566F` 5.2%

## Typography

- h1: 72px
- h2: 72px
- body: 18px

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 16px, 24px, 32px, 48px, 96px — snap all gaps/padding to these

## Radius
- base: 6px
- button: 6px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `lab(64.1687 1.50979 -55.4053)` / `lab(11.9289 1.81083 -27.0733)` | none | 6px | 0px 24px 0px 24px | 500 16px | rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, oklab(0.700292 -0.0321913 -0.154563 / 0.2) 0px 10px 15px -3px, oklab(0.700292 -0.0321913 -0.154563 / 0.2) 0px 4px 6px -4px |
| secondary | `rgba(0, 0, 0, 0)` / `lab(90.9594 -0.472665 -13.5815)` | 1px solid oklab(0.700292 -0.0321913 -0.154563 / 0.15) | 6px | 8px 16px 8px 16px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `oklab(0.700292 -0.0321913 -0.154563 / 0.9)`
- primary focus: outline `1px solid lab(64.1687 1.50979 -55.4053)`
- secondary hover: background `oklab(0.400597 -0.00581403 -0.0437045 / 0.3)`
- transition: `all 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 300ms · 2000ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `linear`
- animated properties: color, background-color, border-color, outline-color

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

## Motion choreography (measured)
Load order: `span.absolute` @0ms → `div.h-full` @0ms
- `span.absolute` — transform none→rotate(360deg) — 4000ms · loops
- `div.h-full` — opacity 1→1 — 2000ms cubic-bezier(0.4, 0, 0.6, 1) · loops
- overlay dialog (auto-opened): panel lab(3.8651 0.063315 -7.29498) · r 6px · shadow 
  - enter: opacity from 0 · 240ms cubic-bezier(0.32, 0.72, 0, 1) | scale from 0.94 · 240ms cubic-bezier(0.32, 0.72, 0, 1)
  - exit: opacity from 0.887588 · 213ms cubic-bezier(0.32, 0.72, 0, 1) | scale from 0.993255 · 213ms cubic-bezier(0.32, 0.72, 0, 1)

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

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px · 1536px · 1600px
- mobile (390px): hero 48px · body 16px · 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.
