 * Alle Styles des Onboardings an EINER Stelle. Design-Upgrade 2026: ruhiges
 * Token-System, klarere Hierarchie, warm getönte Schatten, durchdachte Zustände.
 * Struktur, Bedienung, Feld-IDs und Klassen bleiben unverändert. Aufbau:
 *   0. Schriften (selbst gehostet)     4. Onboarding-Shell (Sidebar, Progress, Nav)
 *   1. Design-Tokens (CSS-Variablen)   5. Feld-Komponenten (Chip, Card, Scale, …)
 *   2. Base / Reset / Animationen      6. Summary + Done-Screen
 *   3. Login-Screen
 * Die Akzentfarbe kommt aus config.php und wird per --l4k-accent gesetzt.
