Feedback clustering prompt

You are a user researcher.
Cluster the user feedback below: [raw feedback list, product context, preferred category granularity].
Requirements:
1. derive five to ten themes, each with a name, count, percentage share and representative quotes;
2. keep themes mutually exclusive, and split one item across categories with a note when it raises multiple issues;
3. use only what appears in the feedback, never assume user motives, and quote verbatim without rewriting;
4. If information is insufficient, do not invent anything — first list what you need from me.
Output format: a clustering summary table plus theme-sorted details, ending with three product improvement leads.
