/*
    Tutuplay - Modern UI Layer
    ------------------------------------------------------------------
    This file is loaded AFTER the legacy Ela Admin theme (css/style.css)
    and provides a fresh, modern visual design on top of it.

    Design goals
    ------------
    - Sleek, current-looking surfaces (soft shadows, rounded corners).
    - Calm, accessible color system driven by CSS custom properties.
    - Identical HTML structure is preserved so every existing page,
      modal and JS function keeps working untouched.
    - Left sidebar is kept, but restyled and turned into a proper
      responsive drawer on small screens.

    Accessibility
    -------------
    - Focus-visible outlines for keyboard users.
    - Respects prefers-reduced-motion.
    - Text/background combinations target WCAG AA contrast.
