// RM Circle: required member profile gate (Marty, 2026-09-16).
//
// The member area only opens once a position has a username and a VERIFIED email.
// It fires the moment ownership is proved (wallet personal_sign, or the Telegram
// Mini App bridge) and cannot be dismissed, because the whole point is that a
// leader can reach every member. The public /my/<id> page is untouched: anyone
// can still read the chain data there, and nobody can write a profile from it.
//
// Usage:  await window.RMCProfile.require();   // resolves once the profile is complete
