/* ============================================================================
   ArgoSat — folha única da landing.
   ----------------------------------------------------------------------------
   Sistema: planta cadastral. Papel cinza-verde frio, tinta de plotter, verde
   pinho como acento e laterita (a terra vermelha) gasta duas vezes na página.
   A camada monoespaçada carrega coordenada, hectare e preço — é dela que vem a
   identidade, não de um efeito.

   Regra de tema: TODA cor sai de token no `:root`. O bloco de
   `prefers-color-scheme: dark` redefine SÓ tokens, nunca componente. Cor
   declarada apenas dentro do media query não existe no estado claro.

   CSP estrita: nada de `style=""`, `<style>`, `<script>` inline ou `on*=`.
