/* ============================================================================
   TortFlow — Marketing site design tokens
   Faithful translation of the tortflow-cdp design system (src/plugins/vuetify.js
   + src/assets/main.css) into a standalone stylesheet. Same brand green, same
   Apple-grey neutrals, same soft diffuse shadows, same Fraunces wordmark face —
   so the site and the product read as one brand. Marketing-only additions: a
   fluid type scale, section rhythm, and the aurora/grain atmosphere.
