/* =========================================================================
   HPayment — UI de pagamento. CSS moderno puro (sem Bootstrap/jQuery).
   Visual CLARO no estilo do checkout HBook (decisão da gerência), com o
   card 3D + logos das bandeiras mantidos como diferencial visual.
   Recursos novos: custom properties, container queries, :has(), nesting,
   color-mix, 3D transforms, View Transitions.
   100% CSP-clean: nenhum estilo inline; tema do hotel via <style nonce>.
