+`--noCache` avoids fable's shared project-options cache, which is keyed by
+fsproj content: reusing it across checkouts of the same project can yield
+spurious `Fable namespace not defined` errors (and even leave a corrupted
+`App.js` behind after a failed compile). The same flag is required in the
+clean-checkout sequence below.

 The server project copies `public/**` into its build output
 (`CopyToOutputDirectory=PreserveNewest`), so rerun `dotnet build` on the server
 after regenerating the bundle.
