/* An author `display` declaration always beats the UA stylesheet's `[hidden] { display:
   none }`, regardless of specificity (author normal > user-agent normal in the cascade) —
   so `.screen { display: flex }` above silently defeated the `hidden` attribute entirely.
   Every screen sat fullscreen with pointer-events:auto at all times, stacked in DOM order,
   intercepting clicks meant for the canvas/HUD underneath. Restore it explicitly. */
