The previous fix paired bg-muted/30 with
supports-[backdrop-filter]:bg-muted/70, intending a fallback for
browsers without backdrop-filter - but every modern browser supports
it, so the 70%-opaque variant was always active and the toolbar read
darker than main at rest. Drop the override entirely: the background
is bg-muted/30 in every state, identical to main, and pinned
legibility comes from backdrop-blur-sm alone (blurring a solid page
background is a no-op at rest; it only softens body text sliding
underneath once the toolbar is pinned).
