/* Raster auf Touch-Geraeten komplett aus — HOCH- UND QUERFORMAT.
   Per Isolationstest (Playwright/WebKit, 390x844 + 844x390) belegt:
   das karierte Muster stammt ALLEIN aus .hero-grid. Gegenprobe:
     - .hero-grid ausgeblendet -> Karo weg, Mauer-Bloecke bleiben
     - #wall-canvas ausgeblendet -> Karo bleibt, Bloecke weg
   Der Canvas (neu.js) zeichnet nur Bloecke (ctx.rect/fill/stroke in
   rgba(0,153,230)/rgba(0,204,255)) und keine Rasterlinien — er bleibt
   daher unangetastet, die Mauer-Animation laeuft auf Mobile weiter.
   display:none statt Opazitaet: auf OLED mit echtem Schwarz blieb das
   Muster selbst bei halber Deckkraft sichtbar.
