   Iteration 35 — one-screen listing page ("apartment.html?route=…")
   The whole residence on one screen: a photo collage on the left (every
   photo reachable through the lightbox), and the identity — title, facts,
   rent, the standard inquiry form — on the right. Monochrome ink/white per
   the system; the listing's own photography carries all the colour.
   The header is forced solid on this page (body[data-header="solid"]).
