3. // ident only, no own passwords (README "How apps use ident" of ident.worldapi.org), the identity selector in the

8. // (POST <ident>/api/exchange) and signs this app's OWN session in
9. // (session.user = { id = <users @id> }, users.hl)
10. // the header's "Log out" button signs this app's session out via the face trackerLogOut (components/main.hl)
11. // — ident's own session, and the browser's ident cookie, are untouched
12. //
13. // Config (env; no committed secret — the first deploy registers this app in ident and sets these, done by the
14. // architect, as with ident's own .env for SMTP):
