/* Shared stylesheet for Wilke Analytics prerendered SEO pages (landing,
   product pages, research articles). Mirrors the app's dark "trading-desk"
   design tokens (see src/design-system/tokens/dark.js) so these static
   pages feel like the same product, not a marketing microsite bolted on.
   Self-contained: no external font/icon/script dependencies besides the
   same Google-Fonts Inter load the app itself uses. */
