 * "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
