Laser hover, 0.8 s: the icon-only circle names itself in a thick-glass capsule 48 px tall, 20 px Semibold, 12 px below it. The text is the circle's aria-label, Steam's own string. It leaves 0.2 s after the laser does.

Gamepad focus on the same circle shows the same tooltip after the same 0.8 s. Bar tooltips are Steam's own popup, restyled by the control-center concept and delayed to 0.8 s. Controls that show their text never get one.
