/* ==========================================================================
   Monolith — Nickel & Swan (options analytics) case study
   The client's product turns the loudest data in finance into one readable
   page, which happens to be this studio's whole thesis — so the page acts
   it out. The hero is a field of raw market static that the cursor combs
   into a clean two-line signal (implied red over historical blue, the
   product's own contract). Sections sit on the platform's light field with
   its deep-purple chrome, screenshots are mounted as the product's own
   card modules, and Nº3 is a working miniature of the volatility module —
   synthetic data, real interaction. Body bg + header adapt per section
   (js/pages/nickel-swan.js). Palette sampled from the shipped UI:
   purple #4F2B83 · implied #FD3700 · historical #0E5FF7 · field #EFF0F3.
   Relies on site.css for resets, nav/footer bones, keyframes.
