#
# .gitea/workflows/ci.yaml  (fleet-kiosk-app repo)
#
# Builds the kiosk SPA into its container image and pushes it, so the fleet
# serving stack `docker compose pull`s it (consumed as a submodule there). The
# Dockerfile compiles the Svelte/Vite bundle (`npm ci` + `npm run build`), so a
# build/compile error fails this job.
#
# Tagging mirrors the fleet serving-image workflows — every branch builds a
# uniquely tagged image you can test without clobbering main:
#   - tag push    (refs/tags/v1.2.3) -> "1.2.3"        (+ :latest)
#   - main push   (refs/heads/main)  -> "main-<sha7>"  (+ :latest)
#   - branch push (refs/heads/<x>)   -> "<x>-<sha7>"   (dev image, no :latest)
#
# Required repo secrets: PACKAGE_USER, PACKAGE_TOKEN (registry creds).
