✅ As a User, I want to join a site with my existing account
Behavior from source: From Join or a comment, follow or bookmark attempt, a browser visitor enters the existing-identity email/passkey flow, confirms the joining account as applicable, and returns to the site as a member with avatar and participation controls. Account-count handling and final CTA have conflicting descriptions in this snapshot.

Source acceptance and behavior
Show Join in the site top bar for nonmembers; Join, comment, follow and bookmark attempts start the same site-context modal.
Name the site, explain Seed Hypermedia and offer Create identity, Already have a Hypermedia identity, and a different-identity-domain option.
The existing-identity path opens distinct Seed Hypermedia branding with Sign in to join [site name]; require a valid email before continuing.
Show the email on the passkey screen and authenticate using biometrics or PIN; Use another email is available.
After passkey success, the written flow shows account/name/email confirmation with copy depending on account count. Single-account step removal and CTA wording are unresolved in the source.
Joining returns to the site as member, removes Join, shows the user avatar, enables comments/participation, and shows a confirmation alert for about three seconds.
Invalid email shows an inline error and disables continuation; unknown email offers creation of an identity.
Email from another domain/site redirects to the another-site identity path, whose details are not supplied here.
Passkey cancellation/failure permits retry or Send a verification code instead; unsupported passkeys automatically offer verification-code fallback.
Use another email returns to email input and clears the previous entry.
Closing mid-flow returns to the site as guest without partial state; browser Back returns to the previous step without losing email.
