/* ============================================================
   AB·PHOTO — design system
   Concept: a darkroom console (rail) opening onto a lightbox
   (content). The rail is a fixed dark instrument panel — home
   of navigation and the workflow order — regardless of theme;
   the content area is where photos and data are actually read,
   so it follows light/dark like paper under an enlarger lamp.
   Palette values are taken verbatim from the validated dataviz
   reference palette (categorical blue = variant B, status
   good/warning = verdict states).
