"""Delete specific fixed_costs rows by id, after showing what they are.

Written for clearing the three smoke-test rows that were inflating the
P&G run rate. Deliberately explicit: it prints each row, writes a JSON
backup of them, and does nothing at all unless you pass --confirm.

    # 1. Dry run — prints the rows and writes the backup, deletes nothing
    python3 scripts/pb-delete-fixed-costs.py <id> [<id> ...]

    # 2. For real
    python3 scripts/pb-delete-fixed-costs.py <id> [<id> ...] --confirm

The backup is a plain JSON array of the full records, so a row can be
recreated by POSTing it back to /api/collections/fixed_costs/records.
