+## 2026-06-23 — gokapi: index redirect + admin username display
+- **gokapi**: seed `RedirectUrl` repointed from Gokapi's GitHub default → `https://${SUBDOMAIN}.${DOMAIN}/admin`.
+  Gokapi's bare root `/` redirects to `RedirectUrl`; the controller's "Megnyitás" link is always the bare
+  subdomain root, so it was landing on Gokapi's GitHub instead of the app. Now `/` → `/admin` → login.
+  Applied to the live demo (config.json edit + restart) and the seed (future deploys).
+- **gokapi**: added `app_info.default_creds` ("Felhasználó: admin · jelszó a Beállítások oldalon") so the
+  app-info page shows the initial admin user like other apps; fixed `first_steps` (no more setup wizard).

 ## 2026-06-23 — gokapi reproducible headless setup (fixes public "maintenance mode")
 - **gokapi**: was stuck in "maintenance mode" on the public URL since first deploy — Gokapi's one-time
   `/setup` wizard was never completed, and (verified against the docs + the v1.9.6 binary) **no Gokapi

+- Gokapi's `RedirectUrl` repointed from the upstream default (Gokapi's GitHub) → `https://${SUBDOMAIN}.${DOMAIN}/admin`,

+## Known minor / optional
 - Seed is tied to Gokapi v1.9.6's `config.json` schema — re-capture if the image is bumped.
+- The controller's "Megnyitás" link is always the bare subdomain root (no per-app path support); apps
+  whose UI isn't at `/` are handled by pointing their index redirect at the right path (as done here).
