# Usage: omarchy-pip [toggle|on] [address:0x...]
#
# "on" always fits the window: float, pin, resize to FRACTION of the focused
# monitor on both axes and park it in the bottom-left corner, inset by GAP.
# "toggle" (the default) does that unless the window is already floating and
# pinned, in which case it unpins and tiles it again. The window defaults to
# the active one. omarchy-summon calls "on" after carrying its window to the
# focused monitor; the YouTube window rule in hypr/hyprland.lua mirrors the
# same fraction and inset for the first open, so keep the three in sync.
