/* =============================================================================
   MindQuest — installable app (PWA) layer
   -----------------------------------------------------------------------------
   Loaded by views/partials/head.ejs on every page, and driven by /js/pwa.js.

   Two things live here and nothing else:
     .mq-install-btn   the optional "Install App" button, hidden until the
                       browser confirms an install is actually possible
     .mq-pwa-sheet     the small dialog that explains Add to Home Screen on
                       iPhone and iPad, where the browser offers no button

   Both are deliberately self-contained. The install button appears on the
   landing page, the login page and inside all four role dashboards, and those
   pages do not share a modal stylesheet — so this file borrows nothing from
   them and leaks nothing into them.
