/* ═══════════════════════════════════════════════════════════════
   EM DOCBOX — shared design system v2
   Source of truth for every module page. Derived from the drugs-page
   native rebuild (2026-06-11), which defines the v2 language:
   · Inter for every UI label (sentence case — never uppercase tracking)
   · IBM Plex Mono ONLY for data values (doses, results, timings)
   · Bebas Neue ONLY for the brand mark + wordmark
   · One page chrome; colour used semantically and sparingly
   · Light theme = token remap on [data-theme="light"], not !important wars
   Pages link this BEFORE their own (small) inline style block and use
   the tokens/primitives below. unify.css must NOT be loaded with this.
