   ÉCHACUENTA — Herramientas gratis para emprendedores mexicanos
   Single stylesheet, sectioned. Mobile-first. No preprocessor.

   Dark-first by design, not a "dark mode toggle": the platform's primary
   background is Onyx, exactly #020202 — not a derived gray, not #111.
   Candy Blue (#B2D5E5) is the one accent, used for text/links/icons
   directly on the dark surfaces (excellent contrast there) and, when used
   as a FILL (buttons/badges), paired with --on-accent (fixed dark text)
   since the accent itself is too light for light-on-light or the reverse.
