/* ============================================================
   RSK4C — site.css
   Vanilla basis- en componentstijlen (vervangt de vroegere Tailwind-build).
   Geen build-stap, geen dependencies. Paginaspecifieke dingen (hero-scroll,
   animaties, portret, preloader) staan in styles.css; de opdracht-wizard
   heeft z'n eigen .wz-* stijlen inline in /opdracht/index.html.

   Opbouw:
     1. Reset          — minimale normalisatie (vergelijkbaar met wat de
                         Tailwind-preflight deed, zodat niets verspringt)
     2. Tokens         — kleuren, fonts, breekpunt (md = 768px, lg = 1024px)
     3. Tekst          — kleur-, font- en maat-helpers (.text-muted, .mono, .title…)
     4. Afstand        — klein setje marge-helpers (.mb-4, .mt-8 …; 1 = 0.25rem)
     5. Layout         — .wrap, .section, .grid-2, .row …
     6. Componenten    — nav, menu, knoppen, kaarten, blobs, formulier, footer
