/* INHERTA public site.

 * Deliberately NOT the React app: these pages must be readable by a crawler
 * that does not run JavaScript. Meta fetches /privacidad during App Review,
 * and the app shell would serve it an empty div.
 *
 * The palette is not decoration. Teal, violet and blue ARE the three channels
 * (WhatsApp, Instagram, Messenger) and they carry that meaning consistently:
 * in the hero streams, in the channel list, in the transcript. They are the
 * product's own brand tokens from packages/web/tailwind.config.js.
