/* Brea 3 — theme tokens + shared styles (Home Screen & Visual Design spec, mockup v4).
   Black · Gold is the default; Cream · Gold is chosen in Settings > Appearance (data-theme on <html>).
   The dark look is WARM (Dee, 2026-10-20, DECISION_LOG "warm dark look — Dee's pick"): the backdrop matches the Aurora's
   measured backdrop (#14100F, top centre #1D1714, top-left glow #2B231D), the gold is a touch warmer and yellower
   (rich, warm, shiny, never mustard or olive), and the glass is near-black, not brown. */
