 * Visual family: RoxyKovu summer palette (dark navy-teal + sand cream) with
 * a sage-forest accent sampled from Catherine's CURA logo, so Cura reads as
 * a sibling of roxykovu.com rather than a separate aesthetic universe.
 *
 *   Page bg:   linear-gradient deep teal
 *   Text:      sand cream
 *   Primary:   sage forest (logo green family)
 *   Secondary: sea foam (RoxyKovu summer foam)
 *   Warm:      sandy gold (warm CTA / highlight)
 *
 * Type: CalSans for display + Rubik for body, self-hosted from
 *       /assets/external/fonts/. Identical to RoxyKovu chrome.
