Vortex follows a hexagonal (ports & adapters) architecture:

  +-------+     +-------------+     +------------------+     +--------+
  |  UI   | --> | Application | --> | Infrastructure   | --> | Domain |
  | Slint |     | Use Cases   |     | HTTP, Persistence|     | Types  |
  +-------+     +-------------+     +------------------+     +--------+

All dependencies point inward. Domain has zero I/O dependencies. Infrastructure implements the ports defined by Application.
