/* ==================================================================
   Depth (upgrade 2026-10-10): gradient light, a faint network texture
   that echoes the hero, layered shadows, raised buttons.
   Contrast holds at both ends of every gradient:
     navy text on #F8B84A..#E08700  >= 6.6:1
     white text on #14149C..#00003F >= 14:1
     amber TEXT uses #8A4E00 on cream/white (5.1:1), never #A85F00.
   Section gradients keep a uniform top edge so the wave from the
   section above (painted in that top color) meets it without a seam.
