#   1. Inside .app bundle: Contents/MacOS/gstack-browser → Resources are at ../Resources/
#   2. Dev mode (run directly): uses global gstack install at ~/.claude/skills/gstack/
#
# Usage:
#   open "GStack Browser.app"          # .app bundle mode
#   scripts/app/gstack-browser         # dev mode (uses global gstack install)
