   PAICON 2026 Redesign — Design System (Phase 1: theme extraction)
   ------------------------------------------------------------
   ADDITIVE + SCOPED. This file does not change the current site:
   - Tokens live on :root but nothing references them yet (inert).
   - All component primitives are scoped under `.pi`, so a page only
     adopts the new look once it (or a section) is wrapped in `.pi`.
   Source of truth: "PAICON NEW WEBSITE ALL COMBINED" prototype.
