/* ══════════════════════════════════════════════════════════════════════════
   Ноктюрн світлий A — page styles.

   The Nocturne design system (assets/css/nocturne.css) supplies tokens and
   component classes. This file holds the light-variant role swap and the
   landing page's own layout, translated from the designer's canvas.

   The canvas was authored at a fixed 1160px. Everything at and above that
   width renders exactly as designed; the breakpoints below it are additions
   for real traffic, and they only reflow — no restyling.
