/* =====================================================
   SuppTree — SVG-Chart-Helfer CSS (gemeinsame Quelle)
   =====================================================
   Struktur-, Typografie- und Animations-Stile für das
   SVG-Chart-HTML, das von shared/charts.js erzeugt wird.

   Namespace: alle Klassen beginnen mit .sct-* (SuppTree
   ChartS) — kollisionsfrei zu anderen App-Stilen.

   WICHTIG: Daten-Farben (Linien, Balken, Slices) werden
   INLINE auf den SVG-Knoten gesetzt. Diese Datei steuert
   NUR Layout, Typografie, Hover/Transitions und neutrale
   Zustände (Gitter, Achsen, Leer-Meldung).

   Die :root-CSS-Variablen (--green-dark, --green-accent,
   --border, --text-muted, --r …) werden von der jeweils
   einbindenden App (hersteller/ bzw. partner/) gestellt.
