/* ===========================================================================
   /como-funciona  +  /en/how-it-works  — page-scoped layer.

   Extends the marketing system defined in main.css. The vibe: an editorial
   long-form walkthrough. Oversized numerals, generous gutters, a single
   accent colour (heritage verde), and real device screens paired tightly
   with each step so the reader never has to imagine what's being described.
