/* ============================================================
   Pagina-bouwblokken — gedeelde opmaak
   ------------------------------------------------------------
   Eén centrale stylesheet voor alle .ambt-* helpers. Wordt
   gebruikt door:
     - page-templates/flex.php   (Flexibele pagina's)
     - single-artikel.php        (Kennis & Inspiratie-artikelen)
     - template-parts/blocks/*   (alle losse bouwblokken)

   Stond voorheen inline in flex.php; hierheen verplaatst zodat
   pagina's, artikelen en blokken exact dezelfde regels delen
   (geen dubbele CSS). Alle selectors zijn .ambt-* geprefixt,
   dus globaal inladen lekt nergens.
