/* Pronota marketing site.
 *
 * Tokens are lifted verbatim from design-language.html :root. Two brand rules
 * bind hardest here:
 *
 *  - Coral (#E05338) is reserved for the active-speaker bar and PRIMARY CALLS
 *    TO ACTION. It is never a background, never decoration. On this page that
 *    means exactly one coral element: the download button.
 *  - The wordmark is Inter Light 300 with ".ai" in Medium 500, rendered as live
 *    text so it cannot drift into another face. It takes currentColor.
 *
 * Dark mode deviates from the design doc deliberately, matching the app: the
 * doc names near-black as the page, but an indigo rail against a black page
 * reads as two unrelated surfaces, so the page is indigo.
