/* Laag: framework. De rangorde staat in skeleton/templates/page.php:
 *   @layer framework, site, theme, type, item;
 * Alles wat het framework meestuurt zit in de onderste laag, zodat site-CSS en CMS-opmaak
 * ervan winnen zonder specificiteits-trucs. Binnen deze laag telt specificiteit gewoon, dus
 * de onderlinge verhouding tussen framework-bestanden verandert er niet door.
 *
 * Een bestand dat deze wikkel MIST staat buiten elke laag en wint daarmee van ALLES —
 * ook van het CMS. `tests/Framework/CodeStyle/ModuleCssIsLayeredTest.php` bewaakt dat. */
