/* ══════════════════════════════════════════════════════════════════
   /tools — Discovery Hub (V3)
   Eigene Schicht, ausschliesslich fuer /tools. Alles ist auf `th-`
   genamespaced (tools hub), damit nichts in die vier Rechner, die
   Startseite oder die Hausverwaltung blutet — die Lehre aus dem
   `.v-note`-Post-it-Bug.

   Tokens kommen aus dem bestehenden Owner: die Seite setzt
   `data-tool-v3` auf den Wrapper und liest damit die V3-Variablen aus
   vertical.css. Kein zweites Token-System, kein neues Orange,
   kein neues Ivory.

   Material wie in der Familie: dunkle Schale als Marken-/Orientierungs-
   rahmen, helle Flaechen dort, wo gearbeitet wird.
   Orange = Aktion · Ivory = Bedeutung · Neutral = Lesetext.
