/*
 * Korzaro marketing landing — standalone stylesheet.
 *
 * Deliberately NOT app/static/shared/brand_tokens.css: the app tokens carry a
 * light/dark admin theme and a status vocabulary a public page has no use for.
 * The palette values below are the same "Obloha" anchors so the two never
 * drift apart visually (sky-600 #256faf is the logo blue), plus one secondary
 * hue the app does not use as a lead colour — lilac #6d52be — so the landing
 * reads as its own surface rather than a screenshot of the admin.
 *
 * No build step and no external requests on purpose: one HTML file, one CSS
 * file, system fonts. Cloudflare Pages serves it as-is.
