/* =============================================================================
   Content Pages
   Shared components for informational HTML-block pages (guide, service pages,
   forwarding, policy pages). Tokens, bare-tag text, headings, divider-top,
   buttons and .hyperlink come from global.css; this file adds only the
   components that need more than a tag. Page-local layout that exactly one
   page uses lives in that page's own <style> block (docs/3.16 Hard Rule 2).

   Every content page roots under `.luna`; component classes are bare and
   semantic, scoped under that root. See docs/3.16-content-pages.md.
