 * vibe: "brand-true, considered, technical, Korean"

 * Palette source: the CK 파트너스 logo, sampled directly.
 *   forest green  #275035  ->  oklch(39.3% 0.065 153)
 *   brass         #bd9e68  ->  oklch(71.5% 0.080 81)
 *
 * Measured contrast, which is why this page is light and not dark:
 *   logo green on dark  #14181b .... 1.94 : 1   unusable
 *   logo green on bone  #fbfaf7 .... 8.80 : 1   clears the 7:1 target
 *   logo brass on bone  #fbfaf7 .... 2.44 : 1   DECORATIVE ONLY
 *
 * --color-gold must never carry body text on this paper. It is for
 * rules, the chevron rail, and fills. Large display text may use
 * --color-gold-deep, which clears 3:1.
