/* Photography gallery
   ===================
   Standalone section: this page reads its own data (photography-data.js)
   and its own images (images/photography, images/optimized/gallery). It
   shares the site's tokens and card language, not its project pipeline.

   Structure
     .photo-hero        image banner (page identity)
     .photo-themes      row of series cards ("All" + one per series)
     .photo-section     one per visible series:
       .photo-section-head   serif title · note · year + count, 3px rule
       .photo-grid           justified rows of photos

   The grid is a justified row wall: each tile carries --ratio (width /
   height from the data file), so a row always fills the container width
   with every photo at the same height. No cropping, no holes, and photos
   stay in reading order.
