   Touch input

   Hover styles live inside `@media (hover: hover)` throughout this project —
   never as a rule that a later query has to undo. On a touch screen the
   browser applies :hover on tap and has no way to clear it (the finger is
   already gone), so the state sticks until you tap elsewhere.

   The query asks about the *primary* input, not the screen size: an iPad with
   a Magic Keyboard reports `hover: hover`, a touch laptop reports whichever
   input the browser considers primary. So this is deliberately not tied to a
   width breakpoint.

   Touch gets its feedback from :active instead, which fires on press and
   clears itself on release on every input type.
