   Автономный файл: префикс `mn-` (menu neon). Не конфликтует:
     — с продом (классы .v-nav, .v-*, .mp-*)
     — с CRO-слоем W4 (классы .cro-*, проверено: cro.css не содержит mn-/nm-)
     — с локальным rebuild-кандидатом (.site-header).
   !important — только в «крайних» блоках: prefers-reduced-motion и print.
   Подключение (патч patch_menu.py делает это автоматически):
     <link rel="stylesheet" href="/assets/css/header-neon.css?v=mn1">
   Деплой-пакет: wave_vis/menu/final/ (SMOKE.md — проверки после деплоя).
