+-- Email-as-identity signup mode encodes an email address as a reversible
+-- big-integer-decimal string behind an "888" prefix and stores it in
+-- users.phone via the existing phone-number column/flow. A real phone number
+-- never approaches this length, but an encoded email can (roughly 2.4 decimal
+-- digits per source byte), so the original 32-char cap (sized only for real
+-- phone numbers) is too narrow. 200 chars comfortably covers realistic email
+-- addresses; see internal/domain.ValidPhone and internal/domain.EncodeEmailPhone.
