10303/// rounded, independently of the actual window tiling state. This is used
10304/// specifically for the workspace switcher sidebar: when the sidebar is open,
10305/// we want square corners on the left (so the sidebar appears flush with the
10306/// window edge) but we still need the shadow padding for proper visual
10307/// appearance. Unlike actual window tiling, this only affects border radius -
10308/// not padding or shadows.
