#### Phase 3: Shifting to URL as Single Source of Truth
We will gradually eliminate React state variables in `src/app.tsx` and derive them (including settings like `standalone`, `showWikiTreeMenus`, and `freezeAnimation`) directly from the `useLocation()` search query parameters on render:
* [x] **Step 3.1a:** Shift `chartType` to URL as SSOT. Derive it using `useMemo` from search parameters, replace calls to `setChartType` with URL updates, and remove the React state variable and sync effect.
* [ ] **Step 3.1b:** Shift `standalone` to URL as SSOT. Derive it directly from search parameters on render and remove its React state variable.
* [x] **Step 3.1b:** Shift `standalone` to URL as SSOT. Derive it directly from search parameters on render and remove its React state variable.
* [ ] **Step 3.1c:** Shift `showWikiTreeMenus` to URL as SSOT. Derive it directly from search parameters on render and remove its React state variable.
* [ ] **Step 3.1d:** Shift `freezeAnimation` to URL as SSOT. Derive it directly from search parameters on render and remove its React state variable.
* [ ] **Step 3.2:** Extract `selection` and `detailIndi` state. Parse them directly from URL params (`indi`, `gen`, and `detail`); update display selectors. Remove React states. Ensure that chart selection changes (`onSelection` callback) explicitly clear or update the `detail` query parameter to match the new selection to avoid getting stuck on the old details viewport. Also update the detail-only selection handler (`onDetailSelection`) to update the `detail` query parameter in the URL.
