/* uitleg-steps.css — scroll-stappen voor /uitleg-pagina's (cowork-stijl).
   Progressive enhancement:
   - zonder JS of op mobiel: nette gestapelde blokken (beeld boven de tekst);
   - met JS op desktop (>=992px): de beeldkolom rechts is een sticky laag over de
     volle schermhoogte met het scherm verticaal gecentreerd; terwijl de stappen
     links langsscrollen wisselt het scherm mee. JS zet de class .usteps--enhanced.
   Herbruikbaar: koppel deze CSS + js/uitleg-scroll.js en gebruik de .usteps-markup. */
