   AD Keukens & Living Design: custom styles

   Tailwind (loaded via CDN in index.html) handles most layout & spacing.
   This file holds only the brand touches Tailwind can't express cleanly:
   the signature divider, the gold line-art motif, animations, and the
   accessibility floor (focus + reduced motion).
   Brand colours are mirrored here as CSS variables so custom rules can use them.
