   Sous-menu « Métiers » — feuille ADDITIVE (Lot M5)
   --------------------------------------------------------------------------
   `style.css` (repris VERBATIM du MPA) ne contient AUCUN style de déroulant.
   Ce fichier est enfilé APRÈS `style.css` et n'introduit que les classes
   documentées `nav-item` / `has-sub` / `nav-sub` / `nav-sub-toggle` /
   `nav-sub-link` / `nav-subnav` / `mobile-link--sub`. Il réutilise les
   tokens de `:root` (--ink, --red, --line, --line-4, --slate-600, --ease,
   --display) et les deux états d'en-tête (`.site-header` / `.scrolled`).
