/* Collection pages (batch 3, approved mockups).
   Untitled 1: a modest contact sheet. Untitled 2: plates, the title then the painting rising through it.
   Urban Decay: the wall kept, then every work whole. Homeless Scribbles: loose drawings that pile up.
   Every page follows the site's light / dark theme. */
