   prose.css
   Markdown-rendered prose styles for Pasteriser.
   Apply with class="prose" on a containing element (e.g. <article>).
   Owns: prose typography. Does not own: markdown→html (use marked/md-it).
   Mirrors the design system's .t-* helpers and CSS vars.

   McMaster brutalist: sharp corners, hard borders, blue links, mono everywhere.
