/* Effect: viervlak — v0.1.0 (nieuw in djturbeau.com v0.3.0)
   De structuur van bkssolutions.be: vier grote vlakken rond één rond middelpunt (hier de draaiende
   plaat) met een tab eronder, en een smalle vijfde band over de volle breedte. Elk vlak heeft een
   eigen kleur (--kl), een kaartje met nummer + titel, en beeld of beweging in het vlak.
   Opbouw: <div class="viervlak"> 4 × <a class="vlak" style="--kl:…"> + <button class="hart"> </div>
   en daaronder <a class="band" style="--kl:…">. Gsm: twee vlakken naast elkaar, plaat in het midden.
   Kost: laag (alleen CSS; hover-gloed en een lichte zoom op het beeld). */
