/* Shadowy — shadowy.studio
 *
 * The page is the Studio. Every token below is the value the iOS app actually uses, taken
 * from Theme.swift, so the hero is a recreation of the real screen rather than an artist's
 * impression of it: same surfaces, same accent, same three bundled typefaces, same controls
 * in the same order.
 *
 * Note there are two greens and they are not interchangeable. --neon (#afff00) outlines the
 * word being spoken; --rec-idle (#a3ff12) is the record button. The app distinguishes them
 * (neonGreen vs studioAccent) and so does this.
