Standalone expenses (date, description, category, amount) with the same equal/own/payer split machinery as entry costs, merged into the costs panel and settle-up as a single expense bucket. Self-fetching card with per-day grouping, client-side sorting, and quick-add. CSV export interleaves expenses with priced entries, one share column per member (UTF-8 BOM, RFC 4180, formula-injection guard on text cells). Also fixes trip deletion, which hit a foreign-key violation and rolled back for any trip with checklist items.
