The composer sent `/goal <objective>` of any length, so an objective past the backend limit (`MAX_GOAL_OBJECTIVE_CHARS = 4000`) only failed after a round-trip with a raw HTTP 422. Mirror the limit client-side: reject an over-length objective before the PUT with a friendly toast, and reject the submit so PromptInput keeps the user's text for editing instead of clearing it. Add a live footer counter that surfaces near the limit and turns destructive when exceeded. Length is measured with the same whitespace normalization the backend applies, so the counts match exactly.
