Scroll-driven animation conversion - apply() writes nothing per frame on the supported path; the hero squeeze, fade line and header curves all ride scroll-driven animations on the compositor. - Section boundaries flip via IntersectionObserver sentinels; the scroll listener is gone from the hot path. - The scrollbar thumb rides its own scroll-driven animation. - @supports-not fallback keeps the previous rAF --p path verbatim, so unsupported engines render identically. - Curves verified exact to 1e-6 against the old path, 0.000px continuity across boundary flips, correct retarget on resize. Perf fixes - Forced-layout reads pulled out of both scroll handlers. - Resize settle-reflow: a second reflow 200ms after resize quiesces, and the pane is observed too. This was the root cause of the fullscreen fade-wedge and of the long-standing intermittent where rows stayed hidden after a resize. Glass - backdrop-filter removed from chips and preview surfaces. - Bar glass blur 20 -> 12. - Choose-hero pill removed from the UI; pickArtistHero/clearArtistHero backend is untouched and the control can be re-homed later. Hero design (final) - Crossfade twins are permanent. Twin blur is baked via bakeBlur() (clamp-to-edge pad -> blur -> crop) so the frames stay pixel-aligned with no edge fringe and no geometry scaling. - Bloom strip retired everywhere; HeroGpuCanvas's internal bloom canvases are hidden by one scoped rule and the component is unchanged. - Seam is a pure mirror: the artwork's top strip flipped inside the glass band, clipped at the bar's top line, riding the squeeze with the hero and dissolving in lockstep on rotation. - GPU twin overlay crossfades on rotation instead of snapping — the incoming baked frame fades in on hero-banner-in with a 2-frame cap. - ~930 lines of experimental variants and the perf-flag system deleted; the surviving path is a pixel no-op against the approved configuration. Debug overlay - PERF/SEAM rows dropped; the overlay keeps stats plus an FPS/drops/worst counter (Ctrl+Shift+D).
