/* ============================================================
   Lipologics — design system v5 "Atelier"
   Editorial light paper alternating with deep plum bands.
   Serif display (Fraunces) + DM Sans. Wine / terracotta on paper,
   apricot / lilac on plum. Each product brand carries its own hue.
   Theming: :root = light paper. .t-dark (and the components listed
   below) re-map the SAME tokens to the dark plum palette, so every
   component works in either context.
