Decoded design system

Missive's decoded design system: background #FFFFFF, text #333333, accent #2266ED, link #050607, primary #2266ED; type scale h1 56px / h2 48px / body 18px; 8px spacing base; 8px base radius. The single interactive/action color is #2266ED — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #2266ED — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #2266ED — one role, not several (the action color).
• accent #2266ED — 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 #050607 — inline text links and link-styled controls.
• secondary #0082F3 — 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.

# Missive — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F2F2F2` |
| border | `#E0E0E0` |
| text | `#333333` |
| text_muted | `#808080` |
| primary | `#2266ED` |
| accent | `#2266ED` |
| link | `#050607` |
| secondary | `#0082F3` |
| button_bg | `#2266ED` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#2266ED` — 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 `#2266ED` — one role, not several (your action color).
- **accent** `#2266ED` — 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** `#050607` — inline text links and link-styled controls.
- **secondary** `#0082F3` — 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` 84.8% · `#DCE1E1` 8.2% · `#5B616F` 7%

## Typography

- Heading: **Tiempos Headline** _(free fallback: Newsreader)_
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 56px / 400 · lh 60px |
| h2 | 48px / 400 · lh 60px |
| h3 | 30px / 400 · lh 36px |
| body | 18px / 400 · lh 28px |
| small | 14px / 400 · lh 21px |

- Weight ladder: 300 · 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Tiempos Headline may be proprietary — safe free fallback: Newsreader (Google Fonts). Inter — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 16px, 20px, 24px, 32px, 48px, 80px, 160px — snap all gaps/padding to these
- section rhythm: 80px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 8px
- card: 8px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#2266ED` / `#FFFFFF` | none | 8px | 12px 12px 12px 12px | 500 14px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#34363A` | none | 8px | 12px 12px 12px 12px | 400 14px | none |

## Shadows (elevation)
- subtle: `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`
- card: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(7, 26, 36, 0.24) 0px 3px 10px 1px`
- overlay: `rgba(0, 0, 0, 0.1) 0px 0px 32px 0px`

## Motion
- durations: 300ms (dominant) · 150ms · 200ms
- easings: `ease` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: opacity, transform, color, background-color

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 108 more measured on the page._

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

## Layout (measured)
- container max 1200px · common grid: 2-col
- nav: 61px sticky

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| -19 | 1244 | 2 | 32 | 160/80 | — |
| 1225 | 292 | 7 | 48 | 48/48 | — |
| 1517 | 703 | — | — | 80/80 | — |
| 2220 | 1834 | 2 | 32 | 80/80 | — |
| 4054 | 1279 | 2 | 32 | 80/80 | — |

## Motion choreography (measured)
Load order: `div.swiper-slide`×2 @0ms → `div.ketch-absolute` @1116ms
- `div.ketch-absolute` — opacity 0→1 — 400ms ease
- overlay dialog (auto-opened): panel #FFFFFF · r 11px · shadow rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(7, 26, 36, 0.24) 0px 3px 10px 1px

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

## Components (measured)
- link: #050607 · underline

## Responsive (measured)
- breakpoints: 480px · 767px · 991px
- mobile (390px): hero 30px · body 14px · 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.
