-- Contact form submissions.
--
-- `subject` is stored as free text (a slug from a known list), not an ENUM.
-- ENUMs need a migration every time an option is added; the list of enquiry
-- types will change more often than the schema should. The controller
-- validates against the allowed set, so bad values never reach here.
--
-- Anti-spam and audit columns live alongside the message: a honeypot outcome,
-- the origin IP, and the user agent. These make it possible to review what got
-- flagged without a separate log.
