Decoded design system

Captions's decoded design system: background #FFFFFF, text #1D1F20, accent #1D1F20, link #7E8486, primary #EFFBFF; type scale h1 48px / h2 32px / body 18px; 4px spacing base; 15px base radius. The single interactive/action color is #EEF4F6 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #EEF4F6 — the single interactive color; only on things you click or must notice, never large fills.
• accent #1D1F20 — accent for emphasis — keep it rare on the page.
• primary #EFFBFF — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #EEF4F6).
• link #7E8486 — reads as a neutral UI color, not a link accent — verify against the reference (action = #EEF4F6).
• secondary #6B7280 — 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.

# Captions — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DDDDDD` |
| text | `#1D1F20` |
| text_muted | `#727474` |
| primary | `#EFFBFF` |
| accent | `#1D1F20` |
| link | `#7E8486` |
| secondary | `#6B7280` |
| button_bg | `#EEF4F6` |
| button_text | `#BEC3C6` |

**Using these colors**

- **Action color** `#EEF4F6` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#1D1F20` — accent for emphasis — keep it rare on the page.
- **primary** `#EFFBFF` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #EEF4F6).
- **link** `#7E8486` — reads as a neutral UI color, not a link accent — verify against the reference (action = #EEF4F6).
- **secondary** `#6B7280` — 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): `#F5F8FA` 71.1% · `#CED3D5` 12.8% · `#7F716B` 9.1% · `#DAECF6` 7%

## Typography

- Heading: **Exposure** _(free fallback: Newsreader)_
- Body: **Denim INK** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 48px / 400 · lh 48px |
| h2 | 32px / 400 · lh 32px |
| h3 | 24px / 400 · lh 24px · tracking -0.24px |
| body | 18px / 400 · lh 23px |
| small | 16px / 400 · lh 21px |

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

> **Fonts —** Exposure may be proprietary — safe free fallback: Newsreader (Google Fonts). Denim INK may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 8px, 10px, 12px, 14px, 16px, 20px, 24px, 40px, 44px, 60px — snap all gaps/padding to these
- section rhythm: 100px top/bottom padding per section (measured)

## Radius
- base: 15px
- button: 8px
- card: 12px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#EEF4F6` / `#BEC3C6` | none | 8px | 10px 16px 10px 16px | 400 13px / 0.3px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#1D1F20` | 1px solid rgb(29, 31, 32) | 15px | 12px 20px 12px 20px | 500 16px | none |

**States (measured, not guessed)**

- secondary hover: background `#1D1F20` · color `#FFFFFF`
- transition: `background 0.15s ease`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.05) 0px 4px 10px 0px`
- overlay: `rgba(190, 210, 235, 0.45) 0px 0px 80px 0px`

## Motion
- durations: 150ms (dominant) · 200ms · 250ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: background-color, transform, opacity, background

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

## Their own tokens (verbatim from :root)

_…and 36 more measured on the page._

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

## Layout (measured)
- container max 1440px · common grid: 3-col
- nav: 74px fixed · backdrop blur(120px)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 1237 | 788 | 2 | 40 | 0/0 | — |
| 2185 | 828 | 2 | 16 | 0/0 | — |

## Motion choreography (measured)
Load order: `header.astro-qjzkj452` @0ms → `div._logos_zq18a_1`×2 @0ms
- `div._logos_zq18a_1` ×2 — transform translate(0px)→translate(-100%) — 20000ms · loops

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

## Components (measured)
- link: #7E8486 · underline — hover #00B7E4
- disabled: bg #EEF4F6 · text #BEC3C6

## Responsive (measured)
- mobile (390px): hero 32px · 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.
