/* =============================================================
   Install-prompt bottom banner
   ─────────────────────────────────────────────────────────────
   Slides up from the bottom edge on mobile when the page-load
   gate in `install-prompt.js` decides to surface it. Hidden by
   default via the `hidden` attribute; JS unsets it and adds
   `.is-open` to trigger the slide-in. Standalone-mode + desktop
   viewports never see this — JS won't show it AND the CSS
   below short-circuits the display for belt-and-suspenders.
