Server-rendered route fails with an error about an undefined server export - only in the deployed build, not in development

Running the production build locally is the habit that removes this whole class of bug, and it is worth stating why development does not catch it: development resolves modules differently and keeps everything in one runtime, so a mismatch that only exists after bundling cannot appear.

Two minutes before pushing. It has caught three things for me this year that would otherwise have been deploy-time surprises.
