/* =========================================================
   TRAVEL NOW — TRÁMITES CSS v1.1
   ---------------------------------------------------------
   Módulo específico para /pages/tramites/*

   PRIORIDAD: base_styles.css (global) manda.
   Este archivo EXTIENDE, no PISA, los tokens y utilidades
   globales del proyecto.

   No redefine:
     :root global, .btn / .btn-primary / .btn-outline / .btn-wa,
     .breadcrumb, .section-label, .container, .wrapper, h1-h4.

   Sólo añade:
     - Variables locales con prefijo --tramites-*
     - Clases con prefijo tramites-* o nombres únicos
     - Modificador .btn-on-dark (extiende .btn-outline)
     - Patrones específicos: hero, timeline, faq, alert,
       cta-block, cards, table.

   Reutiliza variables canónicas seguras del base:
     --color-teal, --color-teal-dark, --color-forest,
     --color-oxford, --color-steel, --color-steel-dark,
     --color-border, --color-bg-soft, --color-bg-card,
     --color-text-muted, --color-success, --color-warning,
     --color-wa,
     --space-*, --radius-*, --shadow-*, --transition-*,
     --font-heading, --font-hero,
     --container-max, --container-pad.

   Evita variables del base que se redefinen al final del :root
   global y cambian de valor (--color-accent, --color-text,
   --color-primary). En su lugar usa las canónicas directas.
