Sale-page filter button is dead on tap
On /collections/sale, we pressed the "Filter" control three times across two page states. No response, no network request, no error — the control simply does nothing on mobile, while the same control works on desktop. Every mobile visitor trying to narrow the sale rack hits a dead end. Screenshot 014 shows the state; the console log is attached.

Fix: the tap handler is bound to an element that's removed at mobile breakpoints; bind it to the visible control instead. Estimated impact if mobile filtering recovers: $900–$1,600/mo. That's an estimate, not a promise.
