/* ------------------------------------------------------------------
   Blade Ball 2D — RETRO 90s / SYNTHWAVE ARCADE skin.
   The game renders to the fullscreen canvas; everything here is DOM
   chrome layered above it.

   STRICT PALETTE (matches shared/config.js PALETTE):
     background   #0a0a0a on a dark magenta → deep cyan radial wash
     neon pink    #FF00FF  — buttons, arena wall accents
     neon cyan    #00FFFF  — panel borders, court lines, chips
     neon volt    #CCFF00  — status text, host controls, the ball

   Z-INDEX ARCHITECTURE (explicit, so layers never fight for stacking):
     0    #game             the canvas — always the base layer
     4    #crt-overlay      CRT scanlines + vignette over the canvas
     5    #hud-hint         tiny in-match corner hint
     15   #spectator-banner persistent "you're spectating" banner
     10   #ui               menu screens (mutually-exclusive .screen children)
     20   #bracket-overlay  tournament bracket, above everything
