/* ============================================================
   The Brainbox² — landing/marketing page styles
   ============================================================
   Nav, hero, sections, testimonial slider, footer. Everything the
   PUBLIC pages share and the two apps do not.

   Extracted 2026-07-30 from an inline <style> block that was
   duplicated byte-for-byte in index.html and en/index.html. It is
   also what /werkkaarte needs — the new page linked only brand.css
   and rendered completely unstyled, which is what forced the split.

   Loaded by: index.html, en/index.html, werkkaarte.html.
   brand.css holds the DESIGN SYSTEM (tokens, buttons, inputs) and is
   shared with app.html/personeel.html; this file is landing-only.
   Add a rule here and it lands on all three public pages at once.
