Build or repair a site's design tokens - colour, type, space, radius, motion - as CSS custom properties with a light and dark theme that are designed rather than inverted, every text/surface pair checked for WCAG contrast by a script, and components that consume roles instead of raw values. Use when setting up theming or dark mode, when colours are hard-coded across components, or when contrast or theme bugs appear.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# /theme-system

A theme is a set of **roles**, not a palette. Components ask for "the text colour for secondary information on a raised surface", never for `#837d88`. Get the roles right and dark mode, brand changes and accessibility fixes become one-line edits.

## 1. Inventory what exists

- Find every hard-coded colour, font size, radius, shadow and duration in the components:

  ```
  grep -rnoE "#[0-9a-fA-F]{3,8}\b|rgba?\([^)]*\)|oklch\([^)]*\)" src --include=*.{css,tsx,jsx} | sort | uniq -c | sort -rn | head -60
  ```

- Group them into near-duplicates. Five greys within 3% of each other are one role used inconsistently.
- Note where each colour is used: as text, as a surface, as a border, or as an accent. Its role comes from its use, not its value.

## 2. Define roles

Keep the set small. Most interfaces need about this:

| Group | Roles |
|---|---|
| Surfaces | `--bg` (page), `--surface` (raised), `--surface-2` (raised twice, or pressed), `--overlay` (scrims) |
| Text | `--ink` (primary), `--ink-2` (secondary), `--ink-3` (tertiary: captions, meta), `--ink-on-accent` |
| Lines | `--line` (hairlines), `--line-strong` (inputs, focus-adjacent) |
…

How to install

The exact contents, by fingerprint

mdr add ham7a311/vitrine/theme-system@sha256:10b4ed0183156beb

The line at the top of this page pins the label git:20261004.15312e4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
