/* StockPools — Arc chain 5042 swap terminal
   Surface: Minimalism HUD + Flat, accent Skeuomorphism (dial). Dark instrument panel.
   Palette: Arc-blue #1F6BFF (sampled from the project mark), slate #2F578C.
   Red is fully retired brand-wide; negative/error states use amber #C9873F.
   Type: Unispace (Typodermic, public domain/GPL/OFL) display + Brass Mono (OFL) data.
   Deliberately divergent from sibling stocksswap-demo (light paper, flat green #008460, DM Sans/Mono, split table). */
