/**
 * banner.css
 * Static styling for the shared UI.Banner celebration slot (banner.js).
 *
 * Layering: the OUTER .achievement-banner owns fixed positioning and centers
 * with margin-inline auto — it carries NO transform, ever, so WAAPI motion on
 * .achievement-banner__body can never dislodge the slot (the historical
 * transform-clobber bug). All motion is transform/opacity on the body and its
 * children, driven by banner.js.

/* ── Banner debug panel (UI.BannerDebug) ──────────────────────────────
   Mounted only under the debug gating triad; developer-facing.

   IT SHARES A CORNER WITH THE LOBBY QUEST RAIL, and it wins. This panel is
   fixed at bottom-left with `z-index: 10500`; the quest rail sits in flow at
   `2100`, so in the lobby the panel lands squarely on the rail's own debug
   buttons and swallows every click. Reported plainly: "debug win buttns
   covered by another debug banner" — and it is why a click that Playwright
   reported as delivered banked nothing.

   Only the LOBBY has that conflict, so only the lobby moves it. In a match the
   bottom-left is free and the panel stays exactly where its user expects it. */

       #feedback-link live. Its padding then swallowed their clicks: with
       `DEBUG_MODE=true` — which the checked-in `.env` carries — four
       feedback.spec.js cases, one gameplay.spec.js case and the real PvP
       rematch spec all failed with "banner-debug-panel intercepts pointer
