Phase 4: component library

The approved element rules and ornament kit as Astro components in
packages/ui: buttons, pills, chips, filters, kickers, notices, fields and
cards; star paths, the header divider, tick scales and rings, seals and
edge seals, gilt corners, dust and placeholder art; the site header,
footer and page shell. Brand fonts are self-hosted. A gallery page shows
everything, and astro check now runs with the root typecheck.
