/* Shoebox. "A shoebox of prints."
   White paper, near-black ink, one marigold accent, and a hard-stop warm
   filmic spectrum hairline. Editorial serif for display, plain system sans
   for UI. Square corners and 1px borders, no soft shadows. Ships a dark
   theme (the darkroom) via [data-theme="dark"]. Light is the default; the
   manual toggle stores the choice in a cookie the server reads on each
   request, so it persists across navigation. */
