/* ==========================================================================
   1. CSS Variables - Studio Focus Palette
   ==========================================================================
   
   Philosophy: This is Aurora Dark with the volume turned down.
   - The primary is Folio's indigo (FOL-N8, UX deep dive 2026-10-23). It was the suite's old
     cyan, so a Folio author saw indigo on the Folio home and cyan in the studio and the
     workspace. Section 2 re-points it at Folio's product tokens; these :root values are the
     same shades, for anything drawn outside the product scope (dialogs).
   - Secondary colors become muted/desaturated
   - Backgrounds shift slightly cooler for extended reading
   - Glows are softer, less frequent
   - The result: same brand, calmer energy
