/* ==========================================================================
   SugarGuard Web — app.css
   Глобальные стили приложения.

   ВАЖНО: Bootstrap полностью удалён.
   Источник токенов: variables.css (единственный источник истины).
   Bootstrap-компоненты (.container, .row и т.д.) здесь не используются —
   всё заменено кастомными SG-компонентами.

   Порядок загрузки в App.razor:
   1. variables.css  — токены (цвета, шрифты, радиусы, тени, spacing)
   2. sg-tokens.css  — compat-алиасы (--sg-* → --color-*)
   3. app.css        — этот файл (base reset + глобальные утилиты)
