/*
 * The site layer's stylesheet (25 October 2026, docs/plannen/sitelaag-eindoordeel.md): linked from every page at this
 * fixed address with a short cache, so a rule here reaches every page within minutes of a web deploy, stored pages in
 * R2 included, without rendering them again. Unlayered: it wins over the build's Tailwind layers.
 *
 * What belongs here: the order and visibility of the header's parts by their data-kop names, its height
 * (--kop-hoogte), the corner of a floating button. Never the content of a page.
 *
 * Empty on purpose until a rule is wanted.
