# User Guide — Signal Noir Dark

## What you received

This product is the fixed theme **Signal Noir Dark**. The palette and appearance are intentionally locked. Other I/US theme editions are separate products and are not included.

The website includes a responsive homepage, projects, posts, local comments demonstration, expandable forms, printing, sharing, company details, social links and offline English/Japanese interface text.

## Quick start

1. Extract the package.
2. Open the `site` folder when using a complete buyer package, or run the `dist` folder from source.
3. Start a local server:

```bash
python3 -m http.server 8080 --bind 127.0.0.1
```

4. Open `http://127.0.0.1:8080/`.

## Edit brand and company information

Edit `content/site-config.json` in the source package. Replace all `example.com`, sample email addresses, company numbers, addresses and social URLs.

## Edit projects and posts

- Projects: `content/projects.json`
- Posts: `content/posts.json`
- English/Japanese interface text: `content/translations.json`
- Placeholder images: `assets/img/placeholders/`
- Post images: `assets/img/posts/`

After editing data, run:

```bash
npm run build
npm run standalone
```

## Fixed theme rule

Do not add a palette selector or appearance switch to this edition. The fixed state is:

```html
<html data-palette="signal-noir" data-appearance="dark">
```

The semantic colour values are in `assets/css/palettes.css`. That file contains only the Signal Noir Dark token set.

## Language

The English/Japanese button remains in the header. It changes interface text offline and stores the preference locally.

## Comments and forms

Comments use local IndexedDB for demonstration. Configure the supplied backend reference before claiming public multi-user comments. Forms use the configured adapter in `content/site-config.json`; the default demonstration prepares an email.

## Deployment

Upload the contents of `dist/` to a static host. See `DEPLOYMENT.md`.

## Attribution

The visible footer credit **Designed by I/US brand.** and its link to https://iusmusic.com are licence conditions.
