Whisperweb's design system, decoded live by Mozaika: measured color roles, type scale, buttons with real hover/focus states, motion and the brand's own tokens.

Decoded design system

Whisperweb's decoded design system: background #FFFFFF, text #0A0A0A, accent #D12200, link #FFF5ED, primary #D12200; type scale h1 72px / h2 60px / body 16px; 8px spacing base; 16px base radius. The single interactive/action color is #D12200 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F0F0F0`
border	`#DADADA`
text	`#0A0A0A`
text_muted	`#676767`
primary	`#D12200`
accent	`#D12200`
link	`#FFF5ED`
secondary	`#EEF4FF`
button_bg	`#D12200`
button_text	`#FAFAFA`

Using these colors

Action color #D12200 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #D12200 — one role, not several (the action color).
accent #D12200 — 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.
link #FFF5ED — 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 #EEF4FF — 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.

# Whisperweb — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DADADA` |
| text | `#0A0A0A` |
| text_muted | `#676767` |
| primary | `#D12200` |
| accent | `#D12200` |
| link | `#FFF5ED` |
| secondary | `#EEF4FF` |
| button_bg | `#D12200` |
| button_text | `#FAFAFA` |

**Using these colors**

- **Action color** `#D12200` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `button_bg` are all `#D12200` — one role, not several (your action color).
- **accent** `#D12200` — 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.
- **link** `#FFF5ED` — 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** `#EEF4FF` — 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): `#FFFFFF` 92.4% · `#6D2C20` 2% · `#D5D6D6` 2% · `#B7A4A1` 1.8%

## Typography

- Heading: **ui-sans-serif** _(free fallback: Newsreader)_
- Body: **ui-sans-serif** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 72px / 700 · lh 72px · tracking -3.6px |
| h2 | 60px / 900 · lh 66px · tracking -1.5px |
| h3 | 48px / 700 · lh 48px · tracking -1.2px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 20px |
| eyebrow | 11px / 500 · tracking 1.65px |

- Weight ladder: 400 · 500 · 600 · 700 · 900 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** ui-sans-serif may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 14px, 16px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 128px top/bottom padding per section (measured)

## Radius
- base: 16px
- button: 10px
- card: 16px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `oklch(0.55 0.22 41.116)` / `oklch(0.985 0 0)` | none | 10px | 0px 20px 0px 20px | 600 14px | 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(0.55 0.165744 0.144669 / 0.2) 0px 10px 15px -3px, oklab(0.55 0.165744 0.144669 / 0.2) 0px 4px 6px -4px |

**States (measured, not guessed)**

- primary hover: background `oklab(0.55 0.165744 0.144669 / 0.9)`
- transition: `background-color 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 300ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0.32, 0.72, 0, 1)`
- animated properties: background-color, 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: `div.flex` @0ms → `span.w-2` @1ms → `div.relative`×2 @627ms
- `span.w-2` — opacity 1→1 — 2000ms cubic-bezier(0.4, 0, 0.6, 1) · loops

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

## Components (measured)
- card ×6: pad 24px 0px 24px 0px · r 16px · border 1px solid oklch(0.922 0 0) · shadow  · bg oklch(1 0 0)
  - hover: box-shadow `` · font-weight `400` · letter-spacing `normal`
- disabled: bg oklab(0.999994 0.0000455678 0.0000200868 / 0.05) · text oklab(0.999994 0.0000455678 0.0000200868 / 0.4)

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 30px · 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.
