/* Figure gallery — layout modelled on the xinye-vis-gallery reference:
   fixed left category sidebar, warm paper background, serif paper titles,
   card grid, and one shared dialog for enlarged figures.

   Palette and typography are scoped to the gallery so the rest of the site
   keeps its own design tokens. Dark mode follows the site's data-theme. */
