   TRADETRACKER — GAP SCANNER STYLES V2

   Design direction: "refined terminal"
   - Dark-first with green/red duotone reserved for data
   - JetBrains Mono for data, Poppins for structure (app defaults)
   - Motion reserved for moments of value (appear, refresh, hover)
   - Heat map inspired by Finviz but cleaner, less ad-y

   All colors use CSS vars from main.css so the 3 themes just work.
