- Full CRUD interface for projects with GitHub integration and tagging
- Real-time event log with expandable metadata viewer
- Reusable component library (Badge, Button, Input, Modal, Table,
TagPicker)
- Server-side API client with Unix socket and HTTP support
- JWT-based authentication with Svelte 5 reactive stores
- Settings management for social links and site identity
- Remove /admin path from tarpit to allow legitimate access
