/* CAN DESIGN WEB STUDIO (2026-10-16 layout).
   The logo is a pastel rainbow disc with a gold rim and ivory letters, so the
   page is quiet around it: warm white, deep plum ink, hair-thin lines, and a
   gold accent for small marks. The rainbow appears only where it means
   something — the logo, a soft glow behind the hero and the contact panel,
   and the thin rule under the header. Pastels never carry text: anything with
   white text on it is ink or --accent. */
