/* Düsseldorf — a daily portrait. Gallery layout: the painting owns the first screen; the honest
   vitals sit quietly below. Mobile-first, dark, art-forward (SPEC §9 Stage F; Constitution Art. 9).
   The visitor reads TIME, never "fresh/stale" — so the "as of" line is styled to be legible, with
   the relative phrase prominent and the absolute local time as a quiet backstop. */
