/* ============================================================================
   REXX DESIGN SYSTEM  —  single source of truth for the whole app
   ----------------------------------------------------------------------------
   Tokens + type ramp + glass primitive are lifted VERBATIM from the design drop
   (docs/rexx-redesign/drop/drop/SPEC.md §2–§3, generated by source/gen.py, which
   itself lifted them from the original rexx_prototype.html). DO NOT re-derive or
   round these; they are already the app's real values.

   COLLISION-PROOF BY DESIGN. Every component/utility/layout class is scoped under
   a `.rexx-app` wrapper, so:
     • legacy pages (which have no .rexx-app wrapper) are never touched, and
     • on a migrated surface the higher-specificity `.rexx-app .x` beats any bare
       `.x` in the old style.css regardless of stylesheet load order.
   Only the :root tokens are global — declaring CSS variables is purely additive.

   A surface adopts the language by wrapping its root in `class="rexx-app"`
   (add `desktop` for the §8 desktop shell) and using the classes below.

   Governing rule (SPEC §2 colour semantics):
     red (--urgent)  = urgency + privilege ONLY, never decorative
     blue (--blue-2) = the system's own voice, active state, executive tier
     green (--ok)    = verified / covered / paid / delivered
     amber (--warn)  = held / pending / declined / at risk
     no emoji anywhere — every glyph is inline stroke SVG on a 24px viewBox
