/* ==========================================================================
   Songbook — "Sanctuary" theme
   A hymnal-inspired look: serif titles & lyrics, hymn numbers set like page
   references, a liturgical plum accent in light mode that becomes warm brass
   in the dark. All colour lives in tokens; components read tokens only, so
   light/dark is a matter of swapping the token layer.
