From 8445e9e8b116d33c2d5bcd8c04d481993b5b639e Mon Sep 17 00:00:00 2001 From: jamey Date: Tue, 10 Feb 2026 15:33:41 +0000 Subject: [PATCH] replace PDP image gallery with scroll-snap carousel Mobile: swipeable carousel with dot indicators, no lightbox trigger. Desktop: carousel with thumbnail grid, prev/next arrows, click to open existing lightbox. Keeps all lightbox appearance and behaviour.
