   TavariLabs — base compartilhada entre sites estáticos
   (calculadora, upload-portal, futuras páginas em site/)

   Cada página define os tokens de tema no próprio <style>,
   antes deste arquivo ser útil: --primary, --primary-dark,
   --ink, --wash, --shadow-soft, --shadow-card, --brand-border.
   Os tokens neutros (cinza, radius, shadow-pop) já vêm prontos
   daqui e não precisam ser redefinidos.
