 *
 * Dark is OPT-IN, not automatic. Keying it to prefers-color-scheme alone means
 * a visitor whose OS is in dark mode gets a black search box embedded in a
 * light WordPress theme, which reads as a rendering bug rather than a feature.
 * The theme setting picks:
 *
 *   .tacus-theme-light  (default) — always light, matches a light site
 *   .tacus-theme-auto             — follows the visitor's OS preference
 *   .tacus-theme-dark             — always dark, for a dark site
 *
 * Everything that changes between the two palettes is a custom property, so
 * the dark values are declared once per selector and nothing else duplicates.
