/*
 * Estilos generales extraídos de resources/views/welcome.blade.php: color, tipografía, barra
 * superior, botones, tarjetas, chips y footer. Mismos nombres de clase y valores que la landing
 * a propósito — el día que welcome.blade.php enlace este fichero en vez de su <style> inline, es
 * un cambio sin sorpresas. No se ha tocado welcome.blade.php todavía.
 *
 * No incluye nada específico de la ilustración de producto de la landing (.dashboard, .phone,
 * .patient-row, .tracking-card, etc.) — eso es contenido del hero, no sistema de diseño.
