/* Shared header/footer/FAQ-search chrome for every public-facing page
   (landing.php and everything linked from its header/footer: about.php,
   product.php, contact.php, training.php, terms.php, privacy.php) - one
   file so all of them stay visually identical instead of drifting the way
   6 copy-pasted <style> blocks inevitably would. Rendered via the matching
   markup in includes/site_chrome.php - see render_site_header()/
   render_site_footer(). Landing-page-only sections (hero, pricing cards,
   features grid, dismissible demo bar) stay in landing.php's own <style>
   block, not here. */
