A mobile-first filter workflow, not a sheet of checkboxes: app-defined groups (checkbox, radio, range, date, search-within-options, hierarchical, custom) with disabled reasons and option counts, a draft-vs-applied model (Apply commits, Cancel restores, Reset, Clear-group/Clear-all), a live announced result count, removable chips, collapsible groups, and an unsaved-change confirm. Ships as a bottom sheet, fullscreen, or desktop side panel with focus trap + restoration, 200%-zoom-safe sticky footer, safe-area insets, and swipe-to-close that is never gesture-only.
