- src/lib/auth/oidc-state.ts (new): pack {state, codeVerifier} into a
short-lived signed JWT, store in an httpOnly cookie. Replaces the
process-local Map that broke under multi-worker deployments where
/api/auth/login and /api/auth/callback would land on different workers.
- src/pages/api/auth/{login,callback,logout,profile,status}.ts: drop the
Map-based state-store calls; use oidc-state for set/get/clear.
- src/lib/auth/oidc-client.ts, session-manager.ts, config/authentik.ts:
small adjustments to fit the new state surface.
- src/components/auth/AuthenticatedLayout.astro, src/layouts/Layout.astro:
trim a lot of layout boilerplate (~125 lines each).
- astro.config.mjs, docker-compose.local.yml: minor cleanup.
- authentik-blueprints/heady-oidc.yaml (new): declarative provider +
application blueprint to ship alongside Heady deployments.
