     chat scrolls via the area around the single product row). The arbiter below

   `.vs-zoom-mode`, which drops the card to bare `pinch-zoom` — removing the
   pan↔pinch ambiguity that otherwise cancels pinch when a finger sits on a card.
   v8.5: arbiter also listens to iOS `gesturestart`/`gestureend` to close most of

/* ============================================================
   LANDSCAPE PHONE — single-scroll layout (v8.4, 2026-05-31)
   ------------------------------------------------------------
   A landscape phone has a very short viewport (often <440px, minus iOS Safari's
   URL/tab chrome). Any fixed header + footer + input leaves almost nothing for
   messages. Instead of fighting for a few px, we drop ALL fixed chrome in
   landscape: the WHOLE modal becomes one natural document-flow scroll container
   (header → messages → footer → input stacked, the whole thing scrolls as one).
   This reproduces the original landscape feel and is the most robust answer to
   the tiny-viewport problem (community rec C "auto-collapse", taken to its
   limit — nothing is pinned, so nothing wastes space).
   How: #vs-modal-inner becomes the scroller (display:block + overflow-y:auto);
   #vs-messages stops being its own scroll area (height:auto, overflow:visible);
   the desktop (arrow) carousel is kept (no mobile pan-x/pinch logic in
   landscape). The JS overlay touchmove handler whitelists #vs-modal-inner
   (v8.4) so this scroll isn't blocked.
   Targeting (landscape + coarse pointer + max-height:540px) excludes desktop and
   landscape tablets. We already use 100dvh, so the modal also grows back the
   ~50px when Safari auto-hides its toolbar on scroll (community rec A).

  /* v8.6 (2026-05-31): landscape uses the DESKTOP (arrow) carousel — no
     horizontal swipe is needed here — so product cards may allow vertical pan.
     Their base touch-action is `pinch-zoom`, which blocked the whole-window
     vertical scroll whenever a finger sat on a card. `pan-y pinch-zoom` lets the
     vertical drag bubble up to the modal-inner scroller AND keeps pinch-zoom.
     No pan-x → no gesture ambiguity → pinch is reliable and NO arbiter is needed
     in landscape (the arbiter only runs on the mobile carousel, hidden here). */
