/**
 * ONSEN — original Tunai theme for bathhouses, spas & saunas.
 * "Night bath": deep charcoal-brown steam, hinoki-wood slat textures,
 * hot-spring blue ripple rings, stone-stack markers and a quiet Zen Old
 * Mincho serif. Scoped under .onsen-theme.
 *
 * Every blue in this sheet derives from --on-spring via color-mix, so a
 * merchant accent re-tunes the whole bath from one variable.
