# cameleer-website — CI (build + test + lint + Lighthouse)
#
# Runs automatically on every push and every PR against main. Does NOT deploy —
# see deploy.yml for that. This workflow exists so every commit gets the full
# quality gate before it can reach production.
#
# Runner: self-hosted arm64 Gitea runner (act_runner).
# Adjust `runs-on` labels if your runner is registered under different tags.
# Architecture note: arm64 build, amd64 deploy is fine — Astro's output is
# plain static HTML/CSS/JS with no arch-specific bits.

      # Lighthouse CI needs a Chrome/Chromium binary at runtime. Google Chrome
      # has no Linux/arm64 build, so we use distro Chromium when available and
      # fall back to Playwright's bundled Chromium (which supports linux/arm64)
      # when not. The Ubuntu runner ships /usr/bin/chromium-browser as a snap
      # forwarder stub that is on PATH but only prints "install via snap" when
      # invoked — so we MUST probe each candidate by actually running it,
      # not just `command -v`.
