   v2 LIGHT EDITORIAL MIGRATION
   ---------------------------------------------------------
   Text already uses the global --dld light tokens (dark), but
   the surfaces were translucent white over a dark page, and two
   bands (scenario question + closing) were dark with dark text.
   Give surfaces solid light backgrounds; flip the dark bands to
   light so their --dld-ink/--dld-muted text reads. The .gsc-code
   block stays dark (its code text is light).
