/*
ARQUIVO: estilos da pagina publica de checkout Early Adopters.

POR QUE ELE EXISTE:
- Mantem visual coerente com a landing octoboxfit.com.br sem repetir tokens da landing.
- Da forma a uma tela "concierge premium": resumo do plano + form curto.

O QUE ESTE ARQUIVO FAZ:
1. Define o shell light com hero magenta sutil para amarrar a continuidade emocional.
2. Estiliza o card de form (4 inputs grandes, dedo-friendly) e o card-resumo (sticky em desktop).
3. Cobre as 3 telas de resultado (success, canceled, manual followup) com a mesma identidade.
