   lf-coach.css — Zentrales LILA-Coach-Modul (V3, 2026-09-12)
   Auftrag: Prompt 25 §5 / Prompt 26 §4.2 — Coach auf JEDER öffentlichen
   Seite als echtes Dialog-Modal, EINE Instanz, kein kopierter Inline-Code.

   REGELN (Projekt-Designregeln, Startseite = Design-Master):
   - Farben, Radien und Schriften kommen aus lf-design.css (:root-Tokens).
   - Der Auslöser verwendet das ruhige Website-/Buttonlila #553BA0
     (Nutzerentscheidung 12.09.2026) — kein Verlauf, kein Schatten,
     kein Leuchteffekt.
   - Die Innenansicht (.conc-*) ist unverändert aus index.html übernommen,
     damit sich der Coach optisch nicht ändert.
