  Soft Edge -- base layer.

  Direction: colourway-led warm DTC. Ribbon colour is the design system. The
  page is cream, the type is a friendly geometric sans in sentence case, the
  geometry is soft (pill buttons, big rounded blocks), and every accent comes
  from the colourway the shopper has chosen rather than from a fixed brand
  hue. No uppercase letterspaced labels, no hairline spec rules.

  Section and page skins live in soft-edge-shop.css.
