feat(theme): introduce retro Windows 98-inspired theme

Add a new "retro" theme option that mimics the classic Windows 98 aesthetic, providing a nostalgic alternative to the modern and classic dark themes.

Changes include:
- Defining CSS variables for the retro theme in `00-base.css` (pixel fonts, silver/gray colors, and classic window shadows).
- Adding custom styling for cards, headers, buttons, and title bars to replicate classic OS windows.
- Adding a star background GIF (`stars1.gif`).
- Excluding the retro theme from modern "revamp" styles in `15-revamp.css`.
- Updating `CLAUDE.md` with instructions on screenshot verification.

/*
* "retro" theme flourishes — modelled on danlegt.com.
*
* Windows 98 chrome over a black pixel-star desktop, PixeloidSans pixel font,
* crisp (non-antialiased, pixelated) rendering. Scoped entirely to
* :root[data-theme="retro"] so it never touches the other themes.
*
* CSP-safe: external stylesheet + self-hosted fonts only (font-src 'self'),
* no inline styles, no remote assets. The starfield is pure CSS so we don't
* depend on img-src for a background gif.
