/* Trading Range and Volatility node (EX-12) — styles. Loaded globally by Dash from /assets, so every rule is scoped
   under .trv-app. The page kit of the main app (assets/app_pages/pages_style.css: .pk-scope, .pk-card, .pk-pills)
   does most of the work; these rules lay out the node like Unconditional Statistics (rail + screens + tiles).
