/* ── Signature pad (SHARED) ───────────────────────────────────────────────────
   Ask Caleb Tech LLC

   Moved verbatim out of driver-app/css/app.css (Aug 2026) when the Time Off
   Request view needed the same pad in BOTH apps. Loaded before each app's own
   app.css, so an app-specific override still wins on equal specificity.

   The touch-action chain is load-bearing and was arrived at the hard way on
   real iPads: wrap = auto, overlay = pan-y, canvas = none. Putting
   touch-action:none on an ancestor blocks scrolling over a LOCKED pad, which
   traps the page. Do not "simplify" it. Depends on the host app's palette
   custom properties (--border, --mid-gray, --error).

  /* Full width. Scroll-vs-draw is solved by the locked-by-default
     "Tap to sign" overlay (built in createSignaturePad): while locked,
     vertical pans pass through the overlay and scroll the page.
     touch-action:none lives on the canvas ONLY — on an ancestor it
     would still block scrolling over a locked pad. */
