// RM Circle: OPTIONAL member profile (Marty + Manson, 2026-09-17).
//
// Contact details are never required to hold a position, get paid, read the org,
// use the training or the tools. Nothing on chain depends on them. They are asked
// for in exactly one place where their absence is the whole problem: a message
// cannot be delivered to someone who has given no way to reach them. Everything
// else is an invitation the member can decline, and declining costs them nothing.
//
// Usage:  window.RMCProfile.prompt({ reason: 'alerts'|'inbox' })  // dismissable
//         window.RMCProfile.edit('username'|'email')              // change later
//         window.RMCProfile.status()                              // read-only
