 **Goal:** Move `areHistoryQueriesEqual` to `frontend/src/utils/` (either into a new `queryUtils.ts` or an existing utility file if a suitable one exists). Import it back into `HistoryPage.tsx` from that location. Verify the function has no implicit dependency on page-local types — if it relies on `HistoryQuery` from `types/history.ts`, it can still live in utils by importing that type.
 
+**Status:** Completed.

 **Possible traps and issues:**
 - This is a mechanical move with no behavioral change. The only risk is a stale import if the function is used in more than one place (confirm with a search before moving).
 - If similar utility functions exist in other page files (a search for `function` declarations inside page files is worthwhile), extract them in the same pass.

 - Move `theme/commonStyles.ts`: if the styles in it are shared across multiple components with no better home, move them to the component directory that uses them most, or rename the file to `components/commonStyles.ts`. The `theme/` directory must contain only `customTheme.ts` and token-related files.
 - For `configStyles.ts` and `blocklistStyles.ts`: inline each exported `makeStyles` hook into the component file that uses it, or keep the file in the same directory as the components but document that it is a style helper rather than a theme definition. The architecture rule is "co-locate styles in the same file as the component" — a shared styles file is acceptable only if documented as an explicit exception for styles used by multiple components in the same subdirectory.

 **Possible traps and issues:**
 - Moving `isoNumericToAlpha2.ts` changes its import path in `WorldMap.tsx` and any other consumer — update all import sites.
 - Moving `api/map.test.ts` to a `__tests__` subdirectory requires the test runner config (`vitest.config.ts`) to include `api/__tests__/` if it only scans `__tests__/` top-level directories — verify the glob pattern first.
