   Near-black ground, warm off-white ink, one flat muted amber
   accent (no glow, no gradient — a nod to phosphor terminals,
   used quietly). System-native faces throughout: a real sans
   stack for reading, a real mono stack reserved for genuinely
   data-shaped elements (dates, tech tags, the LeetCode numbers)
   — never worn as a "technical" costume on body text.
