/*
 * Chief Aim marketing site — same design system as the app, translated to web.
 *
 * Palette is exactly the app's four colors (soft blue / sage / charcoal /
 * white); every other shade is an opacity tint of those four, never a new
 * color. Two faces, two voices: Fraunces is the site's voice (all chrome),
 * Space Grotesk is the words — the aim itself and every button label, same
 * as in the app. Chevrons are the logo's chevron geometry, never glyphs.
