  EDITING GUIDE
  1. TOKENS: change fonts, sizes, spacing, colors, radii, shadows, or widths.
  2. BASE: global element defaults and reusable layout helpers.
  3. COMPONENTS: cookie banner, navigation, buttons, and mobile menu.
  4. SECTIONS: page-specific blocks in page order: hero, trust, services,
     process, results, about, contact, works, and footer.
  5. ANIMATIONS: button animation rules near the buttons and scroll animation
     rules near the end of the file.
  6. RESPONSIVE: changes at 1000px and 900px; these override earlier rules.

  Keep new rules in the section they belong to. Change a token first when
  several elements need the same value; add a local rule only for one element.
