   PowerAdvice — AI Search Overlay
   Morphs from #openSearch (.search-btn.mast-ask) into the colorful AI dimension.

   MOTION TIMING (full motion — prefers-reduced-motion: 120ms root fade only)
   ─────────────────────────────────────────────────────────────────────────
   Anchor: --pa-ask-origin inset + --pa-ask-origin-radius (captureAskOrigin in ai-search.js)

   Stagger ladder (60ms steps; golden-ratio alt ≈ 0 / 97 / 157ms):
     t+0ms   Backdrop  — root opacity + scale; ::before gradient scale/saturate
     t+60ms  Panel     — .pa-search-top, .pa-search-body
     t+120ms Composer  — .pa-composer; ::after scanline sweep

   Durations & easing:
     backdrop fade       180ms  cubic-bezier(0.22, 1, 0.36, 1)   --pa-search-ease-open
     backdrop morph      480ms  cubic-bezier(0.2, 0.9, 0.16, 1)   --pa-search-ease-expand
     panel enter         320ms  cubic-bezier(0.22, 1, 0.36, 1)   delay 60ms
     composer enter      280ms  cubic-bezier(0.22, 1, 0.36, 1)   delay 120ms
     scanline sweep      520ms  cubic-bezier(0.2, 0.9, 0.16, 1)   delay 120ms
     scanline fade-in    160ms  cubic-bezier(0.22, 1, 0.36, 1)   delay 120ms
     close ease          cubic-bezier(0.65, 0, 0.35, 1)           --pa-search-ease-close
     motion complete     660ms  (longest path: scan 520 + 120)    --pa-search-motion-complete

   GPU: will-change while .is-opening / .is-closing (cleared when classes drop).
   Viewport: 100dvh shell + scanline (100vh fallback); safe-area on shell/composer.
