/* ---------------------------------------------------------------- tapping, not zooming
   A child taps "Add one" ten times to build a number. On a tablet the second and third of those taps are a
   double-tap, which the browser reads as "zoom in" — the page lurches and the lesson is suddenly the wrong size.
   `touch-action: manipulation` keeps the tap and drops the double-tap zoom on anything meant to be pressed
   repeatedly, which is every control in a workspace. The page itself still pinch-zooms, so nothing is taken away
   from someone who needs to magnify it.

   `user-select: none` goes with it: repeated taps otherwise start selecting the button's own label, and a child
   ends up dragging a blue highlight around instead of counting. Text they might actually want to copy — the
   tutor's words, the lesson script — is deliberately left selectable. */
