/* ============================================================
   Management System (feature 024) — Register + Record.
   Ported verbatim from the genesis prototype CSS
   (ms-explore/ms-shared.css + ms-explore/direction-b.html),
   renamed to the production `msb-*` namespace the ms-v18.js
   render structure uses, and scoped under `.msb-root` so the
   bare prototype selectors (.dt/.badge/.pill/.btn/...) never
   collide with the app's existing global classes.

   The genesis design tokens (--navy/--ink/--muted/...) are
   redeclared here, mapped to the app's --color-* / --rp-* system,
   scoped to .msb-root. Register area re-matched to the v37
   prototype (feature 045): its visual roles now resolve through the
   corrected semantic tokens while decorative data fills stay unchanged
   (specs/045-v37-ui-parity/reference + scratchpad v37.css).
