/* Options Lab node — styles. Loaded globally by Dash from /assets, so every rule is scoped under .opl-app.
   The page kit of the main app (assets/app_pages/pages_style.css: .pk-scope, .pk-card, .pk-kpis, .pk-pills,
   .pk-chip) does most of the work; these rules lay out the node like Rates & Bond Lab (rbl_style.css).
   Tokens: panels rgba(0,0,0,0.6), chips rgba(255,255,255,0.06), radius 10px, text #e8e8e8,
