    /* Animierter Ellipsis-Loader
       --------------------------------------------------------------------------
       Ausgangswert ist das normale Lucide-Icon #i-ellipsis.
       Die animierte Variante nutzt dieselbe 24x24-Box, dieselben Kreise
       und dieselbe Stroke-Stärke. Dadurch wirken normale und animierte
       Ellipsis optisch gleich groß. Nur die drei Punkte werden per CSS
       nacheinander hervorgehoben. */
