/* ==========================================================================
   IPTV Alberta — Component stylesheet
   Semantic classes for the recurring UI primitives (buttons, badges, cards,
   inputs, tables, accordion, mobile nav drawer, toasts). Loaded BEFORE
   tailwind.css so any one-off Tailwind utility placed alongside these
   classes in the markup naturally wins the cascade for that property,
   exactly like the component/utility layering Tailwind itself recommends.
