// RM Circle member profiles: username + verified email per POSITION.
//
// Why position-keyed and not wallet-keyed: the contract allows one position per
// address, so a Triple Play holder owns three wallets and three positions. The
// person is the EMAIL; one email may hold several positions (that is expected and
// surfaced as "your positions"). Everything else on the site is position-keyed
// too, which is why the existing member-alerts.json seeds straight in.
//
// Identity is only ever written by a session that PROVED ownership of the
// position: a wallet personal_sign (messages.verifyChallenge) or the Telegram
// Mini App bridge. The public /my/<id> page can never write a profile, because
// anyone can open it.
