10284/// The `border_radius_tiling` parameter allows overriding which corners get
10285/// rounded, independently of the actual window tiling state. This is used
10286/// specifically for the workspace switcher sidebar: when the sidebar is open,
10287/// we want square corners on the left (so the sidebar appears flush with the
10288/// window edge) but we still need the shadow padding for proper visual
10289/// appearance. Unlike actual window tiling, this only affects border radius -
10290/// not padding or shadows.
