/* ============================================================================
   Cadence v2 — Design Foundations
   SPEC.md §6.16. Tokens extracted verbatim from the v1 admin layout, which
   already carries the brand's dark/gold identity.

   Rules for every later phase:
     1. Never write a raw colour, radius or spacing value in a view. Use a token.
     2. Never put a <style> block in a view file. That is how v1 ended up with
        600–1000-line views and why the Phase G redesign would otherwise be a
        rewrite instead of a grooming pass.
     3. Safari on macOS is a first-class target — the venue player runs there.
        Every backdrop-filter ships its -webkit- prefix.
     4. Status is a coloured dot PLUS a word. Never colour alone.
