vendored into the pattern, and move copyable starter CSS/HTML out of
the normative contract into README.md.

# Web Visual Baseline — Starter Assets
This file keeps copyable starter code. The normative rules live in `contract.md`.
Canonical reference files (full, production version of the style) are in `assets/`:
- `assets/view.css`
- `assets/view.html`
- `assets/upload.html`
Prefer copying `assets/view.css` directly and adapting tokens. The starter below is a
minimal distilled subset for very small apps.
## Copyable Starter CSS
Use this as the default starting point for new web apps:
```css
