+-- One-shot codes sent by email: the PBKDF2 hash of the six-digit code the player was
+-- mailed, what it is for (`purpose`: a `password_reset`; or an `email_change` — the
+-- current address approving a change — followed by an `email_verify` — the new address
+-- confirming itself — both with the new address as `payload`), and when it was issued and
+-- lapses. One pending code per
+-- account and purpose. Mirrored by EMAIL_CODE_SCHEMA_DDL in @repo/domain's
+-- email-code-db.ts, which says how the row is used — in short, a wrong guess BURNS it
+-- (`code_hash` goes NULL, the row stays for the resend cooldown), a right one deletes it,
+-- and a new request replaces it. Written by `auth` and `accounts`; owned here with the
+-- rest of the account tables.
