   Sree — Colour tokens
   SOURCE OF TRUTH: Sree Figma design-system colour sheet + Sree-app
   app_color.dart. DISCIPLINED PALETTE — do not introduce extra hues:
     • Primary   — Orange 1 / Orange 2 (saffron)     • Positive — Green 1 / Green 2
     • Slate     — neutrals + emphasis (tokens/themes.css)
   Rani-pink secondary, gold, kumkum and the deity/sampradaya accents were
   REMOVED to keep the surface calm. The only functional exception is a single
   critical red (destructive / error). Warning aliases to Primary; info to Slate.
