/* Hidden text input we focus inside a touchend gesture so the OS soft keyboard
   opens on iOS/Android. Constraints that made me pick this exact shape:
     — Must be INSIDE viewport. Safari 16+ refuses focus() on inputs parked at
       negative coordinates (left:-9999px kills the keyboard silently).
     — opacity MUST be > 0 in strict-mode Safari, but any non-zero value works
       (0.001 is invisible even on OLED phones).
     — font-size >= 16px prevents iOS from auto-zooming the outer page on focus.
     — No `pointer-events:none` and no negative z-index: some Safari builds skip
       the OS keyboard for inputs they can't route pointer to, even if we're
       calling .focus() programmatically. It's 1px×1px behind everything anyway. */
