    DASGUARD MOBILE PRO — Complete Mobile Experience Override
    ═══════════════════════════════════════════════════════════════════════
    Loaded LAST in cascade. Every rule is scoped inside @media(max-width:768px)
    so desktop is NEVER affected. Uses high-specificity selectors to cleanly
    override the legacy mobile rules scattered across v12-shell / style / sprint59.

    Breakpoint system (mobile-first within mobile):
      768px  — tablet/mobile entry
      640px  — small tablet
      480px  — standard phone
      390px  — compact phone (iPhone 14/15)
      320px  — mini devices
