/* WakaVoy marketing site.
 *
 * Design tokens mirror bus-portal/tailwind.config.js so the marketing site
 * and the portal read as one product: the same sky/azure brand ramp and the
 * same `ink` neutral ramp.
 *
 * No build step, no CDN, no webfonts. Every byte is served from this host.
 * That is a deliberate choice for the audience: on a Cameroonian mobile
 * connection a Google Fonts round-trip costs more than the visual gain, and
 * an external dependency is one more thing that can be slow or blocked. The
 * font stack asks for the brand faces and falls through to the system UI
 * font, which is already on the device.
