/* Waarom StudyCore (CB, 6 okt 2026): dezelfde vier klussen in drie opstellingen. De stukken schuiven van losse
   apps naar een lijstje dat je zelf bijhoudt naar één route (layout animation, alleen transform).
   Eén onderdeel voor de landingspagina (index.html) en de app (abonnementen.html). De kleuren komen uit de
   pagina eromheen (landing: --cobalt*, app: --accent* met licht en donker thema); de indeling volgt de breedte
   van het blok zelf (container queries), niet die van het scherm. Script: waarom-studycore.js. */
