The frost is the whole window rectangle and the `[data-hud-glass]` scrim is
what makes it readable, but the two ran on different gates: the scrim is
focus-only, while the caller widened the frost to "recent or held" — i.e. for
the whole of a turn. Thinking with the composer unfocused therefore raised a
bare native material with no scrim over it, which on a light theme is a white
slab under the band's unconditionally white ink.
Put the frost back on the scrim's gate, and re-run it on the window's own
focus changes: clicking away to another app fires no focusout, so the scrim
would go while the frost stayed behind.
