# All ports and paths are set by bin/dev via environment variables.
# See bin/dev for the BLIT_DEV_INSTANCE mechanism that makes it easy to
# run multiple stacks side-by-side.
#
#   BLIT_DEV_SOCK       blit server Unix socket    (default: /tmp/blit-dev.sock)
#   BLIT_DEV_UI_PORT    Vite UI dev-server port    (default: 10000)
#   BLIT_DEV_GW_PORT    Gateway listen port        (default: 10001)
#   BLIT_DEV_SITE_PORT  Astro website dev port     (default: 10002)
