// FA renders results inside <section id="gallery-search-results"> with the

// extraction reuses parseGalleryFigure. Pagination is page-numbered (GET
// ?page=N) and the Next anchor is in <div class="pagination"> at the top
// (and bottom) of the results.
//
// useJSON controls the experimental JSON-first merge see parseGalleryPage.
