The CyberQueer GTK4 theme puts `padding: 20px` on the `window` node, which
inflated the layer surface from BAR_HEIGHT (44px) to 84px. The extra 40px is
transparent but still part of the surface's input region, and only 44px were
reserved as the exclusive zone — so the bar hovered over the top of every
window below and swallowed clicks there (e.g. Firefox's address bar).
Zero the window node's padding/margin/border in the bar's own USER+1
stylesheet, and swap the hardcoded set_exclusive_zone(BAR_HEIGHT) for
auto_exclusive_zone_enable() so the reserved zone tracks the real surface
height whatever the theme does. Verified: surface and reserved are both 44px
on all three outputs, and the D-Bus hide/show toggle still releases and
restores the zone.
