/*
  Buchungskalender (Erweiterung „booking“) – kit-neutral: Farben aus currentColor und den Tokens des Kits, damit hell/dunkel und
  farbige Abschnitte ohne Anpassung passen. Zustände sind nie nur Farbe: Text im Feld, Muster, Häkchen.
  Knöpfe/Felder des Formulars kommen aus dataform.css (Kern bzw. Kit).

  Tokens (Standardwerte in @layer booking – jede Regel des Kits ohne Layer gewinnt, egal in welcher Reihenfolge die Dateien laden),
  z. B. im Kit-CSS:  .bk{--bk-accent:#0a5; --bk-muted:#555}
    --bk-kit-accent  Akzent aus dem Kit (sonst --k-accent, --b-btn-bg, … bzw. --dff-accent, zuletzt currentColor)
    --bk-accent      Auswahl, Fokus, Rahmen des gewählten Termins
    --bk-muted       Nebentext (Einleitung, Beschreibung, Wochentage, Zustand im Monatsraster) – muss ≥ 4.5:1 zum Hintergrund haben
    --bk-line, --bk-line-strong, --bk-surface, --bk-sel   Linien, Flächen, Auswahl-Hintergrund
    --bk-free, --bk-partial, --bk-full   Zustände (Text in free/partial ≥ 4.5:1; --bk-full nur für Muster)
    --bk-radius, --bk-gap   Rundung, Abstände
  Die übrigen Regeln liegen außerhalb des Layers (Bauteile sollen nicht von allgemeinen Kit-Regeln wie „label{…}“ zerlegt werden);
  Bauteile im Kit gezielt mit „.bk .bk-…“ überschreiben.
