/* ==========================================================
   SOWAYA | gallery.css
   Gallery page only. Load after base.css and page.css.

   Layout: "justified rows". Every photo keeps its real proportions
   (set per photo as --ar = width / height). A photo's share of its
   row is proportional to --ar, so wide, landscape, square and portrait
   photos line up in even rows with no cropping and no gaps.
   Featured photos are marked with a badge, not resized, so rows stay even.
