 * One-time repair 2026-10-02: the fe_comment tables were created while the

 * and MySQL cannot add an auto-increment PK afterwards. Both tables are
 * still EMPTY - drop them and let extension:setup recreate them properly.
 *
 * Usage: php migrations/drop_fecomment_tables.php
 *        (then: vendor/bin/typo3 cache:flush && vendor/bin/typo3 extension:setup)
