Load when adding cross-system communication, new systems to the main loop, changing game mode logic (editor/dialog/gameplay), or working with camera, input, or mode-switching.

# Intent-Based Architecture Skill

Read the architecture document at `docs/intent-based-architecture.md` (resolve relative to the project root `/home/jonas/projects/snow_trail_sdl/`) and follow its patterns when:

- Adding cross-system communication (use intents, not direct function calls)
- Adding new systems to the main loop
- Changing how game modes work (editor, dialog, gameplay)
- Working with camera, input, or mode-switching logic

Key rule: **systems communicate through typed intent data in shared queues** — producers insert intents, consumers process and remove them. No system calls another system's functions directly.
