# Per ADR-0022 (Documentation site — VitePress).
# Builds the static docs site from `docs/`. On `pull_request` the
# build is a syntax / dead-link gate; on `push` to `main` the same
# build runs and the bundle is uploaded as an artifact so the
# operator can drop it on the static host until the future
# infrastructure ADR locks the rsync target.
#
# Path filter scopes the workflow to changes that can actually
# affect the rendered site: documentation content, the VitePress
# configuration itself, and dependency manifests (Vite/VitePress
# upgrades).
