Decoded design system

Vite's decoded design system: background #16171D, text #FFFFFF, accent #FFFFFF, link #2C1D22, primary #313641; type scale h1 60px / h2 48px / body 18px; 8px spacing base; 4px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #FFFFFF — one role, not several (the action color).
• accent #FFFFFF — 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 #313641 — a brand color — but the call-to-action uses #FFFFFF, not this.
• link #2C1D22 — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #FEBDC5 — 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.

# Vite — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#16171D` |
| surface | `#23242A` |
| border | `#38393E` |
| text | `#FFFFFF` |
| text_muted | `#A6A6A9` |
| primary | `#313641` |
| accent | `#FFFFFF` |
| link | `#2C1D22` |
| secondary | `#FEBDC5` |
| button_bg | `#FFFFFF` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#FFFFFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#FFFFFF` — one role, not several (your action color).
- **accent** `#FFFFFF` — 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** `#313641` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **link** `#2C1D22` — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#FEBDC5` — 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): `#16171D` 89.5% · `#2F173D` 7.1% · `#6D5D63` 3.3%

## Typography

- Heading: **Inter**
- Body: **Inter**
- Mono: **KH Teka Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 60px / 500 · lh 67px · tracking -3px |
| h2 | 48px / 500 · lh 48px · tracking -1.2px |
| h3 | 40px / 500 · lh 53px · tracking -1px |
| body | 18px / 400 · lh 28px |
| small | 16px / 400 · lh 26px |
| eyebrow | 12px / 400 · tracking 0.3px |

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

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 16px, 20px, 24px, 28px, 32px, 40px, 60px — snap all gaps/padding to these
- section rhythm: 112px top/bottom padding per section (measured)

## Radius
- base: 4px
- button: 8px
- card: 6px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | none | 8px | 8px 16px 8px 16px | 500 16px | none |
| secondary | `#14121A` / `#98989F` | none | 8px | 8px 12px 8px 12px | 400 14px | none |

**States (measured, not guessed)**

- transition: `transform 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 250ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- animated properties: opacity, color, transform, translate

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

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

## Layout (measured)

## Motion choreography (measured)
Load order: `a.button` @0ms → `div.testimonial-card`×9 @0ms → `svg.shrink-0` @39ms → `a.button` @213ms → `a.button`×5 @216ms → `label`×5 @216ms

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

## Responsive (measured)
- mobile (390px): hero 36px · 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.
