/* ==========================================================================
   Tiki Tab — tropical design system
   --------------------------------------------------------------------------
   3 themes via html[data-theme]:
     island  "Island Time"    — sunset default
     tiki    "Midnight Tiki"  — dark neon night
     cabana  "Beach Cabana"   — bright day
   Mobile-first. Tap targets ≥ 44px, inputs ≥ 16px (no iOS zoom), safe-area
   insets everywhere, tabular-nums for money, glass cards over fixed SVG
   beach scenes. System fonts only — this app works on a boat with no bars.
