   DESKTOP SHELL (>=1024px)
   A sidebar replaces the bottom nav, the fixed chrome is offset to
   clear it, the content column is centered + capped, and the home
   (Library) screen is redesigned into a search top-bar + tile rails
   + an "All Songs" table. Pure enhancement: below 1024px nothing here
   applies, so the mobile layout is untouched. Deliberately gated on
   width only — kept separate from the height-gated wide-player block
   above (which it must not disturb).
