While a drag is committed the floating bar slides below the screen
edge (UiTransform translation - no layout dirtying, no fight with the
safe-area anchor over Node::bottom) so it never occludes a drop target
on the bottom tableau rows; it slides back on release. Same tween rate
as the label reveal, snaps under reduce-motion. Desktop docked bar is
untouched (no TabBarDuck component).

New Settings::reduce_transparency_mode (serde-default, Accessibility
toggle row) swaps every GlassSurface's gradients for a flat opaque
BG_ELEVATED fill; high-contrast mode now also boosts the glass fill
opacity and rim luminance to BORDER_SUBTLE_HC levels. Both applied by
settings_plugin::update_glass_surfaces, which retargets the gradients
in place on toggle or on newly spawned glass.
