Tailwind className styling retained as an intentional per-surface owner call. 2026-07-07 beta->stable: independently re-verified light/dark + forced-colors of the grid (with and without lightbox) in a real browser. Closed a reduced-motion gap the alpha note missed: the thumbnail hover scale + overlay transitions now carry motion-reduce guards (the GSAP stagger was already gated, but the CSS hover transforms were not). realBrowserForcedColorsVerified + accessibilityTreeVerified set true.",
