/* =============================================================================
   ROADWAYS RADIO — MASTER STYLESHEET (v2, restrained)
   =============================================================================
   India's zero-cost, ad-free highway radio.

   DESIGN NOTES
   --------------------------------------------------------------------------
   v1 leaned on too many decorative Font Awesome icons (clouds, trees,
   milestones, badges) and it read cluttered. v2 strips that back:
   typography carries the page, color and glow carry the mood, and the
   ONLY icons left are functional — playback controls and the single bus
   that drives the highway strip as the page's one signature motion.

   Palette   asphalt #140f0a · asphalt-2 #1d1610 · sunset #e9612d
             marigold #f6b93b · cream #f6ecd9 · dhaba-red #b23a2e
   Type      Display : 'Baloo 2' — bold hand-painted Devanagari weight
             Body/UI : 'Poppins'
   Layout    Mobile-first. #app is a fixed 100dvh CSS Grid shell
             (header / scene / footer). Nothing scrolls — every section
             is sized with clamp() and height-based media queries take
             over on short screens.
