   A terminal-dark marketing page. Two accents, both taken from the logo:
   amber (the wing) marks YOUR code, indigo (the letterform) marks GENERATED
   code. That pairing is the page's one idea, so it is a rule, not a palette:
   if something on this page is amber it is hand-written, and if it is indigo
   Revali produced it.
