 * Fusion aus zwei Stilen, die er beide schon gebaut hat:
 *  - STRUKTUR aus den Elektrotechnik-Guides: DIN-Schriftfeld als Kopf, ruhige
 *    Callout-Klassen, keine Schatten, keine Gradienten, druckbar.
 *  - TOKENS + Theming aus pace-pipeline-phasen.html: dreifaches Theming,
 *    semantische Akzente mit -ink/-soft, prefers-reduced-motion-Notausschalter.
 *
 * v1 benutzt den System-Font-Stack: null Bytes, null Minuten. woff2 (Archivo,
 * Source Sans 3, IBM Plex Mono - alle OFL) kommt in v2.
