# slab-web — open a frameless WEB preview in slab.
#
# Two backends:
#   (default) AC Electron app — chromeless, CDP-attached (:9222), auto-tiles
#             into the terminal grid via the slab menubar's AXTiler.
#   --chrome  your REAL Google Chrome, --app (frameless) mode, using your main
#             profile — so it's logged into everything you are (GitHub, etc.).
#             Best for authed pages (e.g. private PRs). Uses the running Chrome
#             instance (your session); CDP only if Chrome was started with a
#             --remote-debugging-port, and Chrome --app windows aren't
#             auto-tiled (can't be told apart from your normal Chrome windows).
#
# Usage:
#   slab-web <url|path|$code>
#   slab-web --chrome https://github.com/fuserstudio/fuser/pull/608
#   slab-web ~/aesthetic-computer/studies/spatial-flow.html
