   Quran Ayah Player — design system
   --------------------------------------------------------------------------
   A cohesive, premium visual language: Fraunces (display) + Inter (UI), an
   emerald/teal core with a warm gold accent, layered depth, and calm motion.
   Theming is driven by CSS custom properties toggled via
   html[data-theme="light" | "dark"]. `color-scheme` is set per theme so the
   native <audio> controls, scrollbars, and focus rings match.
