/* ============================================================================================
   AWWA online program - responsive layer (WSI26 review, 2026-10-15).
   Loaded AFTER style.css. Desktop keeps the page as it was (sidebar + sessions); below 768px
   the sidebar filters move into a drawer behind a floating "Filters" button, the day chips
   scroll sideways, the session blocks stack, speaker photos shrink and the modal fills the
   screen. Nothing here applies to print (print.css is untouched; the drawer is hidden there).
