/* ── Design Tokens — DELIBERATELY EMPTY ─────────────────────────
   The duplicate :root block that used to live here was overriding
   --ob-accent etc. with the legacy indigo palette. ob-tokens.css
   now owns those variables and points them at the OB blue palette
   via its legacy alias layer. Re-introducing a :root block here
   would silently revert the entire app to indigo — don't.

   shell + projects page — pages like /mapping, /sales, /map-calculator
