/* ═══════════════════════════════════════════════════════════════════════════
   oro-pwa.css — layer 11 · namespace `oroa-`
   Owns: the toast stack, the install affordance, the offline banner.
   Pairs with assets/js/oro-pwa.js. Loaded last. Removable in one line.

   Two constraints from the operating contract are load-bearing here:

   1 · `1rem == 1vw` on this build (inline <style> in index.html), so 1rem is
       3.9px on a 390px phone. EVERYTHING below is authored in px or
       clamp(px, vw, px). Never introduce a rem into this file.
   2 · Additive only. No selector here reaches an element it did not create.

   Occupied space this layer must not collide with:
       .orom-bar   z 4000  · fixed top bar        (≤1024px)
       .orom-drawer z 4500 · slide-in nav         (≤1024px)
       .orom-top   z 3900  · back-to-top, bottom RIGHT, 46px  (≤1024px)
       #oroload    z 99999 · loading plate
   The stack therefore sits bottom-LEFT at z 4600, and reserves the right
   gutter on narrow screens so it never covers the back-to-top control.

   THE INSTALL DIALOG
   ───────────────────────────────────────────────────────────────────────────
   Promoted out of the corner stack. Installing is a decision, not a status
   update, so it gets the middle of the screen and a moment of the reader's
   attention. The transient cards above — offline, back online, update ready —
   stay bottom-left on purpose: they report, they do not ask.

   The motion is deliberately the loading plate's own: the ORO mark draws as a
   stroke and then fills. Reusing the signature the visitor has already seen
   once makes this read as part of the product rather than a browser prompt
   bolted on top of it.

   Everything is px-authored (1rem == 1vw on this build) and every animation is
   transform/opacity only, so it composites on the GPU and cannot cause layout
   shift. Under prefers-reduced-motion the whole sequence collapses to a fade.
