# Open WebUI chat theme

The member chat (chat.inference.coop) is styled to the co-op's house palette
using Open WebUI's **native** `/static/custom.css` hook — no image patching, no
license issues (the branding surface is untouched; we only load styles).

## Files

- `openwebui-custom.css` — the theme (copied to the chat app as `/app/data/coop-theme.css`, served as `/static/custom.css`)
- `figtree-*.woff2` — the four Figtree weights (OFL), copied into the chat app's static dir and served same-origin from `/static/fonts/` (avoids cross-origin font CORS problems)

## How it's deployed

State on the chat app (`50ae6c97-…` on Cloudron):

1. **Persistent copies** live in `/app/data/` (survives app updates):
   - `/app/data/coop-theme.css`
   - `/app/data/fonts/figtree-*.woff2`
2. **Startup hook** in `/app/data/env.sh` (appended, labeled "Co-op theme"):
   ```bash
   if [ -f /app/data/coop-theme.css ]; then
     cp /app/data/coop-theme.css /run/openwebui/static/custom.css 2>/dev/null || true
     mkdir -p /run/openwebui/static/fonts
     cp /app/data/fonts/*.woff2 /run/openwebui/static/fonts/ 2>/dev/null || true
   fi
   ```
   This is needed because Open WebUI's start script recreates
   `/run/openwebui/static/` from pristine image files on every boot.
3. **Live serving** — Open WebUI's built `index.html` already contains
   `<link rel="stylesheet" href="/static/custom.css">`, so no HTML changes.

## To update the theme

```bash
# 1. Push the new CSS to the app's persistent storage
cloudron push --app 50ae6c97-e851-4d17-b013-51ca7a4e5be0 \
  openwebui-custom.css /app/data/coop-theme.css

# 2. Apply immediately (no restart needed)
cloudron exec --app 50ae6c97-e851-4d17-b013-51ca7a4e5be0 -- \
  cp /app/data/coop-theme.css /run/openwebui/static/custom.css
```

## Contrast notes (v2, 2026-09-29)

v1 remapped the full Tailwind gray scale, which drifted body text and
placeholders toward olive and hurt readability. v2 rules:

- **Tint surfaces, not text.** Backgrounds/borders (gray-50..300) get the
  cream/olive treatment; text-side tokens (gray-600+) stay near Tailwind
  defaults in light mode.
- **Explicit text contrast fixes** for message bodies (`.markdown-prose`),
  placeholders, and secondary text, both modes.
- Links darkened to `#3f6e3e` on cream (AA); lightened in dark mode.
