/* ---------- Installation Queue ----------
   Layered on popup.css, which already supplies the overlay, the window, the
   rise animation and the reduced-motion opt-out. Only what is specific to the
   queue lives here.

   The design brief was calm and software-focused rather than commercial —
   Apple, Arc, Raycast, Linear, Craft. In practice that means: more air than
   feels necessary, hairline dividers instead of boxes, one accent and no
   second colour, type that steps down in size rather than shouting, and
   motion measured in a sixth of a second. Nothing here bounces. */

   was: markup borrowing a name the page already owns.
   Reset rather than rename, because <footer> IS the right element here and

   THE INSTALLATION SHEET — phones
   ============================================================

   Not the desktop dialog made smaller. A centred modal is a desktop idea: it
   assumes a pointer, a big screen, and that the thing behind it stays useful.
   On a phone the native gesture is a sheet that rises from the bottom edge,
   sits under the thumb, and can be thrown back down — Apple Music, Maps, the
   share sheet. So that is what this becomes.

   What survives the change is the identity: still a macOS window, still the
   traffic lights, still the mono title. It reads as an August application
   that knows it is on a phone, rather than a website pretending to be an app.
