 - Build scripts in `bs/` – only linting is required at this stage.
 
 ## Tasks
-1. **Environment handling** (TODO)
-	- Create a small helper (`@core/env.ts`) that reads `.env.ts` (or falls back to process.env).
-	- Expose constants: `COMMAFEED_URL`, `USERNAME`, `PASSWORD`.
-1. **API client** (TODO)
+1. **API client** (DONE)
 	- Adds `src/api` folder to the project structure (update also @src/README.md).
-	- Implement a lightweight wrapper around `fetch` in `src/api/index.ts`.
-	- Build `authHeader()` that returns the Basic‑Auth header using env vars.
-1. **Episode service** (TODO)
+	- Implement a lightweight wrapper around `fetch` in `src/api/fetchAPI.ts`.
+	- Build `authHeader()` that returns the Basic‑Auth header using for now hardcoded vars.
+1. **Episode service** (DONE)
 	- Add `src/api/episodes.ts` with `getEpisodes(feedId)` and `getEpisode(id)`.
 	- Add data types
 	- Use `/rest/feed/entries?feed_id=${feedId}` endpoint.
-1. **Route integration** (TODO)
-	- In `app-episodes/routes.ts`, call the service during `enter()` to pre‑fetch episodes.
-	- Pass fetched data via route context or set a global state (e.g., using Lit Labs signals).
 1. **Page update** (TODO)
+	- Add fetching all episodes
 	- Update `<app-episodes>` to reflect loading state(s).
 	- Add episode list item component.
 	- Update `<app-episodes>` to render the episode list received from the route context.
