# hypr-snap.sh
# Move a window in a direction. If already touching that edge, snap to fill
# the full usable area of the monitor (via fullscreen). Stays tiled.
# Works across any monitor configuration.
#
# Usage: hypr-snap.sh <l|r|u|d>
#
# Suggested binds in hyprland.conf:
# bind = $mainMod SHIFT, left, exec, hypr-snap.sh l
# bind = $mainMod SHIFT, right, exec, hypr-snap.sh r
# bind = $mainMod SHIFT, up, exec, hypr-snap.sh u
# bind = $mainMod SHIFT, down, exec, hypr-snap.sh d
