   The look of the promotions and price pages («Контраст»: deep navy, aqua
   highlights, coral actions, big left-aligned headings) on a light base:
   light and dark blocks alternate down the page. Everything is scoped to
   .ab-* so the site header, footer and booking modal keep their own styles.
   Pages are generated by tools/build-about-pages.py.
