/* @abrq/ui prose layer — long-form reading for rendered-Markdown surfaces (G11).
   Plain CSS, tokens only — works in Tailwind apps (apply `abrq-prose` to the
   rendered-HTML container) AND in no-build consumers (G10) that vendor this
   file. Both tiers and `.abrq-invert` come free via the custom properties.

   Voice: calm utility scale (not marketing display), ~70ch measure on flow
   content with code blocks and tables released to the full container width,
   light surface-card code blocks (the DocsDemo precedent — never a dark slab
   inside a light page; `.abrq-invert` is for brand bands, not code), GFM
   tables in the Th mono-caps voice.

   First consumer: abrq-docs. Next: abrq-deliver release notes, dip/mgmt help
   panels. */
