   Predict AI Algo Trading — "Ink & Ember" design system (2026-07-28 rebuild)

   Deliberately NOT the usual algo-trading look. Every competitor (including
   tradealgo.com) ships blue/teal-on-navy fintech. This is warm near-black ink
   with amber/ember accents and an editorial serif display face — closer to a
   financial broadsheet crossed with a trading terminal. Distinctive, and it
   suits an evidence-first brand better than neon.
