/*
 * Flute of the Soul — design system
 * ---------------------------------
 * The site carries two worlds: a macOS desktop shell and Krishna's bansuri.
 * What joins them is sound. A flute only speaks when breath passes through
 * emptiness, and the work here is real-time voice AI — so sound is the thesis,
 * not ornament. Marcellus carries the mythic voice, Sora the engineer's, and
 * JetBrains Mono the measurements.
 *
 * Loaded after styles.css so it re-skins the existing Mac shell in place.
 */

/*
 * Palette — a white theme in the feather's own colours.
 * On light ground the accents must carry real weight, so the teal and gold are
 * pulled dark enough to pass contrast on white (peacock #0F7A6E ~4.8:1,
 * gold-ink #8A5E12 ~5.6:1). The bright teal is kept for large marks only.
