/* --------------------------------------------------------------- 2. hero
   Three planes behind the copy: the generated far image, a thin cyan
   horizon arc (mid), and a dark near arc whose top edge overlaps the
   bottom of the CTA block by 8px (same trick as the homepage hero:
   plane-near's height is the hero's own padding-bottom + 8, so with no
   min-height forcing extra space, the arc's top edge always lands 8px
   above where the content naturally ends). z-index: plane-far behind
   everything (0), scrim + plane-mid + plane-near as one background group
   (1, paint order by DOM position), hero-inner on top (2) -- copy always
   wins, the near arc only ever shows through empty space beside it. */
