+# Notes for Claude (and humans) — SchulyWebsite
+
+Angular 20 marketing site for [schuly.dev](https://schuly.dev). **Bun is the package manager** (no npm, no `package-lock.json`).
+
+## Run / build
+
+```sh
+bun install
+bun start            # ng serve on http://localhost:4200
+bun run build        # production build → dist/SchulyWebsite/browser
+bun run watch        # dev build with file watching
+```
+
+Required bun version: `1.2.21+` (text `bun.lock` format isn't readable by 1.1.x). Pinned via `packageManager` in `package.json` and `cli.packageManager` in `angular.json`.
+
+## Build output
+
+Angular 20 uses `@angular/build:application` builder → output at `dist/SchulyWebsite/browser`. **Cloudflare Pages is configured for that path** — verify if you change `angular.json`.
+
+## Deploy
+
+Cloudflare Pages deploys `main` automatically via the GitHub integration (Cloudflare dashboard, not a workflow).
+
+Cloudflare build settings:
+- Build command: `bun run build`
+- Output: `dist/SchulyWebsite/browser`
+- Env: `BUN_VERSION=1.2.21`
+
+The `.github/workflows/build.yml` CI is independent — it only verifies the build passes on PRs so broken code is caught before Cloudflare attempts a preview deploy.
+
+## Add a feature
+
+Stack is plain Angular standalone components. Look in `src/app/`. SCSS, no Tailwind. FontAwesome via `@fortawesome/angular-fontawesome`.
+
+## Release
+
+Driven by `application.properties` like the other repos. `sync-version-on-release.yml` updates both `application.properties` **and** the top-level `version` in `package.json` when a release is published.
