/* ============================================================
   GEO SPARK · 3D + Glassmorphic overlay
   Loaded after geo_spark.html inline styles to override them.
   Goals:
     1. Make every floating panel translucent + frosted ("glass").
     2. Shrink the main left rail by default so the map dominates.
     3. Add a fullscreen Cesium container that sits BEHIND the panels.
     4. Add HUD chrome (mode bar, avatar, POV vignette, reticle).
