/* ==========================================================================
   DAN ANDREWS — one page

   Built in the same grammar as granite.coach: two tones and a single accent.
   Black and white carry everything. One mint green is permitted exactly once,
   on the correction in the hero — the moment the sentence changes its mind —
   because that gesture is the whole idea, and colour that means one thing keeps
   meaning it. Nothing else is ever green.

   Every neutral is mixed from --fg, so the whole page flips with two swaps and
   the accent stays put. Fonts are self-hosted; the page calls no third party.
