1. // project.hl — tracker.worldapi.org: STEP 1 (tracker.worldapi.org#1), an empty shell. Login copied unchanged from
2. // calendar.worldapi.org (rejected once for a centered sign-in and no header selector — architect, 2026-09-27):
3. // ident only, no own passwords (README "How apps use ident" of ident.worldapi.org), the identity selector in the
4. // header (components/main.hl). No shows, no data yet — later steps come from the creator (CONCEPT.md).
5. //
6. // the header's ident-selector / "Log in with ident" -> <ident>/login?key=&return=<this app>/login/callback
7. // /login/callback?ident_code=<code> the app's server exchanges the code for the identity's short id
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):
15. // TRACKER_PORT (45008), TRACKER_URL (this app's own public address, for the return URL),
16. // IDENT_URL (https://ident.worldapi.org), TRACKER_KEY (pk_…), TRACKER_SECRET (sk_…)
