/* kapitel/applet.css — gemeinsamer Rahmen für alle Applets (alle Seitentypen).
   Übernommen 1:1 aus elektroskop/ (.es-*) und polarisation/ (.pol-*), generisch benannt.
   Einbinden NACH der Typ-Datei (inhalt.css, uebungsseite.css, …) und NACH fach.css:
     <link rel="stylesheet" href="/assets/css/kapitel/applet.css">
   Farben kommen ausschließlich aus var(--fach-ink) / var(--fach-strong) (fach.css),
   damit derselbe Rahmen in jedem Fach die Fachfarbe trägt. Nichts hiervon in eine
   Seite kopieren — seitenspezifisch bleibt nur die Zeichnung selbst. */
