/* Lyadneva theme - design v2 "golden hour" (2026-09-24).
   One sand background for the whole page; colour changes only where a photo or a dark block enters.
   One photo language: the photo dissolves into the background (hero, dark blocks, breaks).
   Source of the design: design/v2/page.html (tools/build_page.py). */
