   Release Notes Viewer — 360 Hextile
   Scoped to .release-notes-md. Wraps render_markdown() output on the public
   index cards, the public detail page, and the admin release detail preview,
   so all three surfaces read identically.

   Dark-first, warm industrial, minimal. No glow, halo, neon, or gradient
   chrome (design-system AI Slop blacklist #9). Brand is carried by the link
   underline and the list marker only.
