Add HandlerRegistry::register_handle for generated Handle<T> values and migrate examples away from passing raw numeric handle ids at registration sites. req: ceremony/004 req: public_api/001
slhx Kanban browser example
Run:
cargo run -p slhx-kanban-example
Open http://127.0.0.1:3001.
The example is a server-first Kanban board with:
- add-card form
- move-left / move-right card controls
- delete-card controls
- generated handle ids and slots
- application/slhx EffectBatch responses
- SSE presence updates
It intentionally uses buttons instead of custom JavaScript drag-and-drop; drag/local-first sync remain north-star features in examples/kanban.md.
