Borlander

Borlander is a MV3 browser extension that applies a classic Borland blue/yellow theme globally, with optional site-specific overrides.

Site-specific themes (automatic)

Any folder under borlander/sites/<site>/styles.css is treated as a site theme automatically.

• If the folder name looks like a hostname (e.g. github.com), it matches when the current page hostname includes that string.
• A couple themes are heuristic-based (currently sonarr.local, gitea.local) because they may run on custom domains. Those are defined in borlander/scripts/generate-themes.mjs.

The registry lives in borlander/themes.json and is loaded by both content.js and popup.js.

Regenerate themes.json

If you add/remove site themes in borlander/sites/, re-generate the registry:

node borlander/scripts/generate-themes.mjs
