/*
 * Estilos de joingivi.com. Sale del diseño del dueño (web.html) casi tal cual;
 * lo que cambió y por qué:
 *
 *  - Los mosaicos usan las fotos reales en vez de gradientes CSS.
 *  - El verde de TEXTO es más oscuro que el de marca: #10C795 sobre blanco da
 *    2,2:1 y AA pide 3:1 para títulos y 4,5:1 para texto normal. El verde de
 *    marca se queda en lo decorativo y sobre fondo oscuro, donde sí contrasta.
 *  - No hay estilos en línea en el HTML: la CSP no permite 'unsafe-inline'.
