/* ═══════════════════════════════════════════════════════════════════════
   ¡CACHAI! — SCHIEFERTAFEL (0.30.4)
   Die Tafel ist die Erklärstimme der App: Regeln, Konjugationsmuster,
   Beispiele. Übungen und Vokabeln bleiben Papier.

   KONTRAKT:
   · --etp-font-hand (Playwrite CL) wird NUR hier referenziert.
     tools/design-lint.py meldet jede Nutzung außerhalb dieser Datei.
   · Alle Slate-Farben leben als --etp-slate-* / --etp-chalk-* Tokens
     ausschließlich in dieser Datei.
   · Ein Deko-Element (Wisch-Schatten), sonst nichts. Vivaldi, nicht
     Pavarotti.
