   SPHRAGIO — Design Tokens (PR-D2b, ADR-0025)

   The single source of design tokens consumed by all three surfaces:
   the upload page, the live result page, and the standalone HTML export.
   The export INLINES this file verbatim (zero external requests); the live
   surfaces LINK it from base.html. Defined once here — do not re-declare
   these custom properties elsewhere.
