2 * LSXC-25 / LSXC-28 — Portable continuous Alliance logo strip (template 143291).
3 * Cursor agent change — 2026-07-24
4 * Ticket/context: LSXC-28 — suppress logo link activation after drag
5 * See: .cursor/plans/lsxc-28-alliance-slider-drag-click.plan.md (chat LSXC-28)
6 *
7 * Continuous auto-scroll + click/drag for every embed of template 143291.
8 * v1.0.9 — drag-vs-click guard: only pure clicks open logo URLs.
