| `Ctrl+1` | Actual size (1:1) |
| `F` | Toggle FIT / 1:1 |

### Other Features

- **Drag & drop** images onto the canvas

```

The HTML annotation engine is entirely self-contained — no external fonts, no CDN JavaScript, no build step. The PyQt6 wrapper adds native file dialogs, menu bar, CLI image loading, and dark window chrome via a `QWebChannel` bridge.

The HTML also works standalone in any browser for quick use without Python.
