/* =====================================================================
   Oil Pressure Fix · Gleitlager im Querschnitt, Stribeck-Kurve, Öldruck-Soll
   Ein Messplatz in der Detail-Kachel (#oilSim im Dialog #simDlg-oil): die Bühne (WebGL-Druckfeld
   und Ölpartikel, darüber die Zeichnung in Canvas 2D), daneben Umschalter, Messwerte, Regler und
   Stribeck-Kurve; danach Erklärung, Kennfeld und Wirkungskette. Die Vorschau in der Kachel zeichnet
   oil.js selbst in ein eigenes Canvas (.oil-pv).
   Raster 2026-10: Desktop drei Spalten (Bühne | Messwerte und Regler | Stribeck),
   Tablet Bühne breit darüber, Telefon eine Spalte mit breiter, flacher Bühne.
   Farbe als Ereignis: Bernstein nur für Festkörperkontakt (Mischreibung).
