/* ===== VARIABLES =====
   Los mismos azules y verde agua del logo de PMS que usa el panel (ver public/styles.css). La
   landing mantiene variables propias porque no carga Bootstrap ni styles.css: es una página
   suelta. Los nombres son de ROL (`dark`/`main`/`mid`), no de color — así el próximo cambio de
   marca no deja un `--green-*` pintando azul, que es exactamente de donde venimos.

   Los tres tonos fuertes pasan AA sobre blanco (9.0:1, 6.1:1 y 5.4:1) y aguantan texto blanco
   encima con los mismos números; los dos claros son solo fondos. */
