Subject: [PATCH] Fix lock icon getting blurred with its container, tune
 overlay look

filter/opacity on the container recomposited its whole subtree
(including the lock icon appended as a child) as one filtered unit, so
the icon's own filter:none/opacity:1 couldn't opt it back out. Switch
to backdrop-filter on the overlay instead, which only blurs what's
painted behind it, leaving the icon crisp with no need to reparent the
site's own React-owned DOM.

Also lighten the blur (pixelated on small pills) in favor of
grayscale/brightness doing the "disabled" signaling, and size the
overlay 4px larger on every side than a flush inset:0.
