/*
 * Air Mouse product site.
 *
 * Shares its design language with the other Azayn product sites (e.g. dev.health.azayn.com): dark surfaces,
 * Geist, floating pill navigation, glass cards with gradient hairlines, big tight headings. The token names below
 * (--color-*, --font-family-*, --shadow-*) are the same as the Health site's, so the shared neutrals can later be
 * lifted into a common azayn.com stylesheet. Only the brand colours differ: Air Mouse is azure, not green.
