/* zdarkroom.css — loaded via zMeta.zBrush: [zdarkroom] -> /styles/zdarkroom.css
   Teaching goal: a before/after processing studio (zList/%item of TWO zImage
   side by side + measured stats) plus a file-upload zDialog that hands off to
   a plugin doing REAL PIL transform work. Dark "darkroom" theme (deep charcoal
   + amber safelight accent) so it reads as a distinct product from zGallery's
   light portfolio grid, not a reskin of the same card. */
