    Contrast is measured through the whole compositing chain, not against an
    assumed opaque panel:

      SVG pixel -> --scrim over it -> --backdrop-filter applied to that group
                -> --panel-bg over that -> --chip-bg over that -> text

    Checked at both extremes of the artwork (its white bloom and its darkest
    floor fill). --text-faint is the tight one: it sits on --chip-bg, a second
    translucent layer, in .video-meta and .region-note.

    Light theme, measured: text 13.7-16.1:1, muted-on-chip 6.4-7.4:1,
    faint-on-chip 4.8-5.6:1, field border 3.7-4.4:1 (needs 3:1).

    Re-measure these if --scrim or --backdrop-filter changes: a lighter
    scrim lets more of the artwork through and lowers every figure here.
