`overflow: hidden` on the frame and its body cut a control's 22px
`--gl-glow` dead at the clip edge, and the gauge's own `<svg>` cut its
drop-shadow at the viewBox — the arc's top sits ~3.5 units from it.
`overflow: clip` with a margin wide enough for the blur (1.5rem on the
body, which already sits 1rem inside the frame; 0.5rem is all that leaves
the tile, which is the gutter).
That means the body no longer scrolls by default. `.dui-frame-scroll` was
already wired through from `scrolls()` into every look's Surfaces with no
CSS rule behind it, so the class is what opts markdown, agenda and
notification back into a real scroller.
