We did this because old maps could acrue and we're being checked in. At some point our binary size started ballooning. Are we sure parcel cleans up old versions properly now? |

Why
Release documentation bundles advertise
sourceMappingURLreferences, but.js.map/.css.mapwere only embedded in Debug builds. Production therefore served guaranteed 404s, which blocks Lighthouse and debugging tooling from attributing work to source modules (#3689).What
Embed Parcel-generated JS and CSS source maps in all configurations so they ship alongside hashed bundles. Serving, cleanup of old hashed maps, and static extraction already supported
.mapfiles — only the Debug-only embed gate needed to change.Closes #3689
