/* ===== Melray design tokens =====
   Style reference: "Function" (warm apothecary journal on parchment) —
   parchment canvas, aged-paper surfaces, warm-taupe hairlines, ink text and
   ONE red-to-orange accent (CTAs, eyebrows, active states only). Elevation
   comes from color stepping; the only shadow is --shadow-float.
   Light is the default theme; [data-theme="dark"] on <html> (set by
   js/theme-init.js, toggled by js/main.js) overrides the theme-sensitive
   tokens below. --color-accent picks a lighter red-orange on dark for
   contrast. */
