# Gallery

Static photo gallery for logging meals and food memories.

The site is based on the HTML5 UP Lens template and currently ships as a plain static site: HTML, CSS, JavaScript, and local image assets.

## Repo Layout

- `templates/index.html`: source template for the main gallery page
- `index.html`: generated static gallery page
- `assets/`: site CSS, JavaScript, fonts, and audio
- `images/fulls/`: full-size gallery images
- `images/thumbs/`: gallery thumbnails
- `data/meals.json`: source of truth for gallery entries
- `scripts/build.js`: renders static pages from templates and data
- `scripts/generate-thumbnails.js`: regenerates thumbnails from the full-size images
- `package.json`: minimal Node build entrypoint

## Content Workflow

Gallery entries live in `data/meals.json`, and `index.html` is generated from `templates/index.html`.

After editing content or templates, rebuild the site with:

```sh
npm run build
```

The build currently renders the main page without changing the existing Lens gallery structure, so the current client-side viewer code continues to work.

If you only need to regenerate thumbnails, run:

```sh
npm run build:thumbs
```

To force a full thumbnail rebuild, run:

```sh
npm run build:thumbs:force
```

## Image Conventions

- Full-size images and thumbnails share the same numeric ID
- Full-size images live at `images/fulls/<id>.jpg`
- Thumbnails live at `images/thumbs/<id>.jpg`
- `position` controls the full-screen viewer image alignment
- `thumbnail.focus` optionally overrides the default center crop for generated thumbnails

## Thumbnail Focus

Thumbnails are generated from `images/fulls` with `sharp` at `240x320`.
The generator auto-rotates images using EXIF orientation, skips unchanged files by default, and removes stale thumbnail `.jpg` files that no longer map to a meal entry.

For images that should crop away from the center, add optional thumbnail focus metadata to the meal entry:

```json
{
  "id": "34",
  "title": "example",
  "description": "example",
  "thumbnail": {
    "focus": {
      "x": 0.35,
      "y": 0.45
    }
  }
}
```

The `x` and `y` values are normalized from `0` to `1`, where `0.5, 0.5` is the center of the image.

## Planned Features

1. Automatic image ingestion, potentially with a stronger data model if the static workflow becomes too limiting.
2. An Elo-style ranking page that shows two food images at a time and updates rankings automatically based on the selected winner.
3. General cleanup and history cleanup once the bigger structural changes are in place.
