/* Baseline for every touch surface in the app: drops the ~300ms tap delay
   and disables double-tap-to-zoom, without blocking ordinary scrolling or
   tapping into a field. Screens that own a custom drag gesture (swipe home,
   pan the sky) override this to touch-action:none so the browser never
   competes with that gesture for the touch -- without *some* touch-action
   rule, a mobile browser is free to interpret a horizontal drag as an
   attempted page gesture and cancel the pointer sequence mid-swipe, which is
   what made swipe/tap feel unreliable on phones. */
