   DT²⁵⁶ DESIGN SYSTEM LAYER — v2.05 (2026-08-12)
   Purely additive stylesheet, loaded LAST so it can refine earlier sheets.
   It never changes behaviour: every selector targets presentation only, uses
   the existing theme variables (light + dark both keep working), and degrades
   gracefully in older browsers (color-mix guarded by @supports).
