## Branches

**Open pull requests against `dev`, not `main`.**

`dev` is where everything is integrated. `main` only ever moves through a
release: it is fast-forwarded from `dev`, tagged, and the tag triggers the
Docker image publish. A PR against `main` would put unreleased code into the
branch that is supposed to match the published image — so please branch off
`dev` and target it.

CI runs on pull requests to either branch, so a PR against `dev` is checked
exactly the same way.

If you opened a PR against `main` by accident, no need to redo the work — you
can change the target branch on the PR page under **Edit** next to the title.

## Development setup

```bash
# 1. Clone and switch to the integration branch
git clone https://github.com/ralksta/immich-folio.git
cd immich-folio
git checkout dev

# 2. Install
npm install

# 3. Configure
cp .env.local.example .env.local
cp content/gallery.yaml.example content/gallery.yaml
# Edit .env.local or set IMMICH_API_URL + IMMICH_API_KEY

# 4. Run
npm run dev       # http://localhost:3000
npm run build     # production build check
```

## Before submitting a PR

```bash
npx tsc --noEmit   # must be 0 errors
npx vitest run     # all tests must pass
npm run build      # build must succeed
```

## Code style

- **TypeScript** — strict mode, no `any` without justification
- **Components** — Server Components by default; use `'use client'` only when necessary
- **CSS** — vanilla CSS variables, no Tailwind, no CSS-in-JS
- **Naming** — descriptive names, no abbreviations in public APIs
