/* ============================================================
   Woningopname — visueel ontwerp (Toevast v2)
   Brand-trouw aan de Toevast brandguide (Ifthen, april 2022):
   - Blinker als hoofdfont (lokaal, geen CDN)
   - Exacte palet-waarden uit het brandboek
   - Beeldmerk als markering in de topbalk
   - Donker thema (default) via brandguide's "diapositief"-treatment
   - Licht thema (auto via prefers-color-scheme) = canonieke
     Toevast-look: Lichtgrijs canvas, wit verheven, Donkergrijs tekst
   Klassennamen en HTML-structuur ongewijzigd; app.js werkt zonder
   aanpassingen.
