/* Nelavista shared design system — extracted verbatim from templates/landing.html.
   This is the canonical "general CSS" for every public-facing page (landing, login,
   signup, forgot/reset password, about, privacy-policy). Some selectors here (hero,
   features, founder, cta) are only used by landing.html itself — that is fine, an unused
   CSS rule costs nothing; what matters is every public page pulling from ONE file instead
   of copy-pasting (and drifting from) their own version of the same variables/nav/footer/
   buttons. */
