Decoded design system

Things's decoded design system: background #F2F5F7, text #303336, accent #4F91FB, link #5C9CF5, primary #2576EB; type scale h1 36px / h2 24px / body 18px; 4px spacing base; 7px base radius. The single interactive/action color is #4F91FB — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #4F91FB — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #4F91FB — one role, not several (the action color).
• accent #4F91FB — 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 #2576EB — a brand color — but the call-to-action uses #4F91FB, not this.
• link #5C9CF5 — fails contrast on the background (~2.5:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #55606E — 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.

# Things — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#F2F5F7` |
| surface | `#E6E9EB` |
| border | `#D4D7DA` |
| text | `#303336` |
| text_muted | `#797C7F` |
| primary | `#2576EB` |
| accent | `#4F91FB` |
| link | `#5C9CF5` |
| secondary | `#55606E` |
| button_bg | `#4F91FB` |
| button_text | `#5C9CF5` |

**Using these colors**

- **Action color** `#4F91FB` — 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 `#4F91FB` — one role, not several (your action color).
- **accent** `#4F91FB` — 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** `#2576EB` — a brand color — but the call-to-action uses #4F91FB, not this.
- **link** `#5C9CF5` — fails contrast on the background (~2.5:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#55606E` — 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` 93.6% · `#A8A8B8` 6.4%

## Typography

- Heading: **Roboto**
- Body: **Roboto**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 36px / 700 · lh 36px |
| h2 | 24px / 400 · lh 30px |
| body | 18px / 400 · lh 24px |
| small | 16px / 400 · lh 21px |

- Weight ladder: 400 · 600 · 700 · 800 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 3px, 4px, 7px, 10px, 13px, 18px, 23px, 27px, 29px, 36px — snap all gaps/padding to these

## Radius
- base: 7px
- button: 6px
- card: 18px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#5C9CF5` | none | 6px | 4.05px 10.125px 4.05px 10.125px | 600 20.25px | none |
| secondary | `#FBFCFE` / `#5C9CF5` | none | 6px | — | — | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`

## Shadows (elevation)
- subtle: `rgba(38, 52, 74, 0.15) 0px 1px 0px 0px`
- card: `rgba(0, 0, 0, 0.1) 0px 2px 8px 0px, rgba(0, 0, 0, 0.1) 0px 0px 2px 0px`

## Motion
- durations: 100ms (dominant) · 200ms
- easings: `ease-out` (dominant)
- animated properties: transform, background

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

## Components (measured)
- link: #5C9CF5 · no underline

## Responsive (measured)
- breakpoints: 420px · 734px · 739px · 899px · 972px · 1002px
- mobile (390px): hero 20px · body 18px · nav: inline

## 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.
