/* ============================================================
   SONG WORLDS (Sept 2026)
   One stylesheet for the song-world overlay on the music page AND the
   standalone song pages in /songs/, so the two can never drift apart.
   Each world paints with its song: --w-base (the ground), --w-accent,
   --w-glow, and --w-text: the accent as type (labels, the Malayalam title,
   the page's button), which a song can set a step lighter when its accent
   is too deep to read at small sizes on its ground (palette.text).
   ============================================================ */
