   engraving); inside it a wide gold-gradient child (.plate-energy-flow) slides

   the travelling highlight shows ONLY on the engraved contours — the light
   crawls the lines. The engraving is shown as its own static <img> beneath;
   this layer just adds the moving glint.

   WebKit-safe (dock recipe, layout.css): real child on its own compositing
   layer (translateZ(0)), animates transform/opacity ONLY — no filter, no easing
   appended to a motion token. Under reduced-motion the flow rests off-plate

   Both PvP modals (#battle-modal 1v1, #match-modal stable-vs-stable) now ride

   Phase 0). These rules add the Phase-2 art on top: the VS cartouche emblem,
   engraved HP chrome, victory/defeat verdict plates, and the brass reward
   plaque. Every asset is wired with a CSS fallback (a tinted box / the existing
   gradient / a hairline box-shadow) so the modals render correctly BEFORE the
   PNGs exist — same "generate out-of-band, then it lights up" pattern as
   Phase 0. WebKit-safe: texture layers sit on REAL children, animate nothing
   but opacity/border-color/transform, no filter anywhere.
