name: Bun

# Bun is the SECOND supported runtime (framework >= 5.4 is certified on
# Bun >= 1.4) — it gets its own workflow so a Bun regression reads as "Bun
# broke" without turning the Node run red. The matrix tests the declared
# floor and the latest stable; `fail-fast: false` so a floor break and a
# latest break never mask each other. Locally the same suite runs through
# Docker instead: `docker compose --profile bun run --rm backend-bun`.
