/* =====================================================
   GIXO STUDIO - AURORA DARK (FOCUS VARIANT)

/* ==========================================================================
   1. CSS Variables - Studio Focus Palette
   ==========================================================================
   
   Philosophy: This is Aurora Dark with the volume turned down.
   - Cyan (#00d9ff) stays as primary — it's the Gixo signature
   - Secondary colors become muted/desaturated
   - Backgrounds shift slightly cooler for extended reading
   - Glows are softer, less frequent
   - The result: same brand, calmer energy
