### Tauri advantages
- Installer sizes: 2.5–10 MB (vs. 80–150 MB for Electron)
- Idle memory: 30–40 MB (vs. 200–300 MB for Electron)
- Sub-second startup times

### Code signing requirements
- **macOS:** Apple Developer Programme (£79/year) + notarisation mandatory. Unsigned apps trigger "damaged app" dialogue.
