   Palette avoids the generic AI-design defaults (no cream+serif+terracotta,
   no near-black+single acid accent, no broadsheet hairlines) — instead a
   deep-ink "flight deck" base with three functional accents (teal=live/ok,
   amber=attention, coral=negative), and tabular mono numerals for data.
