What
The local preview server that serves generated pages can now serve JavaScript as well as HTML. When a previewed page references the Mermaid diagram script, the server loads that bundle on demand and serves it as text/javascript, so diagrams render without reaching the network.
Details
Each served entry is now a body plus its own content type, rather than everything being forced to text/html; charset=utf-8.
If the bundle cannot be read, the failure is swallowed and recorded as a mermaid_bundle_unreadable telemetry event; the page still loads without the diagram script.
Evidence
mermaid_bundle_unreadable
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
