/* ==========================================================================
   Престиж Мебель - prestijmebel.com
   Palette family: forest green + cool stone. One accent, locked page-wide.
   Corner radius: 0 across the whole page (cabinetry logic).
   Photos sit in an inset mat with a hairline, like a mounted panel.
   Theme: light by default, real dark mode via prefers-color-scheme.
   Motion: entry choreography + scroll-driven parallax, all reduced-motion safe.
