Introduced a request-scoped `Map` (`authCache`) in `app/api/map/route.ts` to memoize `isAuthenticated` calls.
The `getMapData` loop iterates over all albums across all locations. Albums within the same subpage slug trigger repeated `isAuthenticated` checks, which execute expensive HMAC cryptographic operations, causing performance degradation for large datasets.
Eliminates redundant cryptographic operations during map data fetching, reducing CPU utilization and response times for the Map API.

Replaced the unbounded `Promise.all` in `getMapData` with a chunked
fetching approach. This prevents Out of Memory crashes by limiting
the concurrent fetching of large arrays of assets to chunks of 10.

Avoids unnecessary O(N) memory allocation and copy by returning `Buffer.from(...)` directly since Buffer inherits from Uint8Array in Node.js.

Extracted the grid mapping logic out of the return block into a `useMemo`
hook depending on `[assets, layout, openLightbox]`. This prevents the
entire photo grid—including complex Next.js `<Image>` and `<FadeIn>`
components—from needlessly re-rendering every time the user navigates
via the lightbox arrows or presses next/prev buttons, which previously
caused `lightboxIndex` to update and trigger a re-render of the entire grid.
