 * The few things that are shared across every page: the colour and type
 * tokens, the reset, the app's skeleton (`.app`, `.kopf*`, `.haupt`,
 * `.bahn`), buttons, the overlay frame, the empty-state note, the fab, the
 * form fields and the toasts. Everything else -- the pills, the
 * cards, the settings panels, the throw field -- is a component's own CSS,
 * added once through `styleOnce()` where it is used (`WEB.§10`).
 *
 * The values are the mockup's (`esmusssein/mockup/index.html`, 9-804); the fonts
 * are given as a list with system fallbacks rather than fetched from a CDN
 * (`WEB.§2`), so the roles they mark -- serif for what esmusssein wrote, mono for
 * what somebody threw in -- hold even where IBM Plex is not installed.
