/* ═══════════════════════════════════════════════════════════════
   TABLA VISUALIZER — Tamil Bookshelf MIDI Player
   tabla-visualizer.css  v2.0.0  (2026-05-20)

   FIXES in v2.0:
     • bolHitCentre animation: translateX(-50%) was missing from
       intermediate keyframes causing a jump on #bz-48/#bz-46/#bz-47
     • Hover transform conflict resolved — centred zones use a
       data-centred attribute approach via :is() selector
     • Added .bayaan-active / .dayaan-active glow (referenced in JS
       but missing from CSS)
     • striking-hand z-index raised above combo pads (was 30, now 35)
     • Waveform canvas properly visible on all viewport sizes
     • Minor: combo bol-zones position:static preserved in .tabla-combos
