   ADMIN DASHBOARD COLLAPSIBLE FILTER
   Exclusive to app/templates/admin_dashboard.html — moved out of
   index-filter.css (which is exclusive to the public index page) so the
   two pages' filter panels never share a file. Restructured from three
   paired min+max-width bands into a mobile-first, ascending min-width-
   only cascade per CLAUDE.md 6.3, eliminating the dead zone that
   occurred at fractional viewport widths near 767/768px and 1023/1024px.
