/* ==========================================================================
   UploadHub — app-specific components (dropzone, vault/file list, stat
   cards, admin tables, hero, public link page). Loaded ALONGSIDE
   assets/css/site.css (shared dilman.dev nav/chrome + design tokens) on
   every page. Uses the exact same CSS variables as site.css — no new
   color values are introduced here, so the whole app matches the
   de.dilman.dev look 1:1.
