/* ==========================================================================
   TaxBackAir

   Design brief: this product asks strangers for money and for their booking
   documents. Every visual decision is therefore a trust decision. The look
   is deliberately closer to a payments company than to a claims agency —
   restrained palette, strong typography, generous space, real hierarchy.

   Constraint: the CSP is `default-src 'self'`, so no web fonts and no
   external assets. Everything below is system fonts, CSS and inline SVG.
