   Direction: alternating warm-white and full-bleed navy panels, one gold
   stroke line as the recurring motif ("The Line"), glass surfaces,
   layered navy-tinted shadows, bento layouts, spring motion.
   Locked: palette, type, two radii (0 / 4px), gold enforcement list.
   One banner per copy-deck section, in order.
