/**
 * Tests for the print speed control feature on the PrintersPage.
 *
 * The printer-card refactor in #1661 replaced the visible "100%" / "50%"
 * speed badge with an icon-only Gauge button. These tests now target the
 * button via data-testid="speed-control" instead of the percentage text.
 * The dropdown still shows the same translated labels (Silent (50%),
 * Standard (100%), Sport (124%), Ludicrous (166%)).
