METIS App: Invite — Signup

Placeholder. A usage guide for the Invite signup experience has not been written yet. A full usage doc — walking an invitee through the public sign-up pages — is deferred to its own future doc pass rather than drafted as part of the initial docs outline.

When written, this page will cover the invitee's experience of the public sign-up pages (the global invite page and per-holon "local gathering" pages): what they see, how they sign up, and what happens next.

Invite lives under web/invite, not metis_apps/, but is grouped as its own app-level section for consistency. The page builder side (for admins configuring these pages) is internal engineering documentation, not part of this public manual.
