 ## Phase 3: Core Callbacks

 ### 3.1 Reference data loading + filter state management
- [ ] Create `dash_app/callbacks/filters.py`:
+- [x] Create `dash_app/callbacks/filters.py`:
  - `load_reference_data` callback: fires on page load, calls `queries.load_initial_data()`, populates `reference-data` store + header indicators
  - `update_app_state` callback: fires when chart-type toggle or date dropdowns change, computes `date_filter_id` (e.g., `"all_6mo"`), updates `app-state` store
  - Chart type toggle: use `callback_context` to determine which button was clicked, set active class via `className`
- [ ] Create `dash_app/callbacks/__init__.py` with `register_callbacks(app)` that imports and registers all callback modules
- [ ] Wire `register_callbacks(app)` in `app.py`

 - **Checkpoint**: Page loads reference data, filter dropdowns update app-state store (verify via browser dev tools → dcc.Store)
