   NewsFeed — licht, verzorgd thema (bewuste afwijking van het
   donkere neon-thema dat de rest van de workspace gebruikt), met een
   optionele donkere variant. Categoriekleuren staan NIET meer als losse
   --cat-*-tokens hier — sinds bronnen/categorieën in SQLite leven
   (src/sourceRegistry.js) komen kleuren rechtstreeks uit de API-data en
   worden ze als inline style toegepast (zie app.js/admin.js); een vaste
   tokenlijst hier zou na een categoriewijziging in het beheerscherm stil
   achterhaald raken.
