# make/demo.mk — end-to-end proof of the repo flow on three demo repos
#
#   examples/demo/demo-api     standalone API
#   examples/demo/demo-web     calls demo-api  (.den.yml compose.uses)
#   examples/demo/demo-notes   unrelated, standalone
#
# Each repo carries its own Makefile (run it alone) and .den.yml (how
# den runs it: compose behind the HTTPS edge, no host ports).
#
#   make demo           register + up + check + restart + down, then clean up
#   make demo-register  workspace "demo" with the three repos
#   make demo-apps      den apps: "shop" (declared by the repos) + demo-notes (its own)
#   make demo-up        den up -A shop (demo-api first), then demo-notes
#   make demo-check     HTTPS through the edge (retries ~10s while the edge
#                       picks up new routes); demo-web shows demo-api's answer
#   make demo-status    den status
#   make demo-restart   den restart -A shop
#   make demo-down      den down, every demo repo
#   make demo-clean     down, drop the demo workspace + catalog entries, refocus
