   site.css — shared design system for the Fleet Tracker marketing pages
   (index.html, partners.html). Single source of truth for the theme tokens,
   nav/header, buttons, hero, sections, cards, contact form, and footer.
   Page-specific rules (comparison table, pricing, steps, margin panel) stay
   in each page's own inline <style>, which loads AFTER this file so it can
   override where needed.
