   projecten.css — Hands of Luxury Clean (R4D5)
   --------------------------------------------------------------------------
   Pagina-specifieke styling voor de Projecten overzichtspagina
   (tpl-projecten.php). Bouwt voort op tokens.css, base.css en
   components.css. Wordt conditioneel geladen via enqueue.php.

   R4D5 changes (Sprint 4, Ronde projecten):
   - Editorial hero (links uitgelijnd, geen gesloten content-card)
   - Filter-chips rij bovenaan de grid
   - Featured-first layout: 6-kol grid, item 1 spant 4 kolommen
   - 14-item grid met editorial project-nummering (01–14) op beeld
   - Category-label + plaats als editorial meta-byline
   - Numerical trust-stats (4-kolom) i.p.v. 3 USP-cards

   Alle kleuren via --hol-* tokens. Animatie via .rv / .rv-scale
   (site.js IntersectionObserver). Filter-logica in projecten.js
   — werkt via [data-active-filter] op de grid en [data-category]
   op de cards (CSS doet het verbergen, JS zet alleen het attribuut).
