/*
 * Dialog "Was ist neu" of the CFML apps (markup: cf-shared/ui/changelog).
 *
 * A native <dialog>, so it needs no framework: focus trap, Escape and the top layer come from
 * the browser. Colours follow Bootstrap's tokens where the page has them - including its dark
 * mode via data-bs-theme - and fall back to the system colours otherwise. An app with its own
 * palette sets them through the argument cssClass.
