/* =============================================================================
   ARCHIVE.CSS — Shared styles for /treks, /packages, /stays archive pages
   All three use the same structural pattern:
     .hih-archive-hero → page hero with count pill
     .hih-archive-wrap → .hih-archive-sidebar + .hih-archive-main
     .filters-sidebar  → sticky filter panel (radio groups)
     .hih-chips-row    → active filter chips
     trek-grid / stay-grid → card grids (defined in global.css)
