Follow a city, or change its notifications
PUT
/cities/{slug}/follow
Idempotent. Creates the follow with the defaults (weekly digest on, instant alerts off) or changes only the switches given. The bell on the city page sends both false to silence a city without unfollowing. 404 when the city has no page.
Authorizations
BearerAuth
In the browser, authentication rides on the httpOnly session cookies set by /cognito/signin or the Google / Apple sign-in at /cognito/oauth/{provider}. For scripts and for Swagger UI testing, paste an API key (fh_live_…, created with POST /api-keys); a Cognito JWT is accepted too. Sign-in does not return a token in its body.
