 * Brand-locked: these values are the app's own palette, lifted from
 * App/iOS/Design/Theme.swift (墨 sumi ink · 藍墨 aizumi · 和紙 washi paper ·
 * 朱 shu accent · 萌葱 moegi) and converted to OKLCH so the web surface and the
 * two apps stay the same product.

 * Axes — paper band: dark (L 15%) · display style: mono · accent hue: warm (32°)
