Remove console log, update error message

Editor assessment

Honest, well-formed housekeeping: style(common) pairs a sensible scope with an imperative subject, and removing a stray console.log needs no body. Two things hold it back. First, "remove console log, update error message" bundles unrelated tweaks — cleanup and a content edit — so the type choice straddles chore and style and settles for neither; separate commits would be cleaner. Second, "update error message" is maximally vague about content: which message, what was wrong, why the new wording? A reader scanning history learns that maintenance occurred but nothing transferable. Perfectly acceptable as a small, scoped cleanup specimen; weak teaching value beyond the format itself.
