/* HVO creator morph popup — carousel level-up Task 4 (2026-07-19).
   Spec: docs/specs/2026-07-19-carousel-levelup-design.md §4; plan Steps
   4.2–4.4b. A wheel card FLIP-morphs into this theme-aware squircle
   card: 16:9 mlplayer on top (video creators), identity row (48px
   avatar = the FLIP target, channel name, subs count-up), delivered-
   language flag chips, VIEW CHANNEL pill (GET STARTED fallback when a
   creator has no channelId). Backdrop = rgba dim +
   blur(8px) MAX (small-items ledger: 18px full-viewport over video
   janks the Studio Display; the hero is paused via HVOMediaBus anyway).
   Theme: light #fff / dark #232323 (dark surface hierarchy, README).
   z-order: layer 9990 · FLIP clone 9995 · mobile see-pill 9996 — all
   below the fx cursor dot (99999). */
