   Telugu Gospel Lyrics — UX POLISH LAYER (Phase 10.5, v3.2.1)

   ADDITIVE ONLY. This file does not redefine brand tokens, does not change
   typography families, and does not restyle existing components beyond
   spacing / touch-target / focus refinements. It loads last so its rules win
   without needing !important.

   Sections:
     1. Hero (search-first)
     2. Alphabet grid
     3. Category cards
     4. Song summary card
     5. Discovery + linking rails
     6. Sidebar
     7. Footer discovery mesh
     8. Search page
     9. Skeletons + empty states
    10. Accessibility + motion
