The severity stripe draws after the alert lands.

It scales out of the arrow, not out of its own centre. One transform-origin placed on the anchor point does the whole job, and it stays correct when the popover flips side.

The shell blurs in first, results cascade after. Both under 200 ms in production.

The scrim fades first and the panel arrives a beat later. The exit is faster and travels less than the entrance, because leaving should not ask for the same attention as arriving.

A four-point polygon opening past the corners. Percentages beyond 0–100 are what make it cover.

It grows out of the edge nearest the trigger, not out of its own middle. The transform-origin is what carries the relationship; without it the card looks unrelated to what opened it.

Moving the transform-origin during the animation bends a straight translate into an arc. One property, no path.

It lingers at 87° as a thin slit before it turns flat. The pause is the whole effect.

The exit is the part nobody gets for free. allow-discrete animates all the way to display:none. Baseline since 08/2024.

500 ms before the first one, 0 ms inside the same group.

The list overshoots, then settles back.

The button springs, the particles leave.

It rests on a snap point before it goes full height.

The opening stalls at a third of the way before completing. The stutter is deliberate and it is what names the family.

A new message pushes the stack back and down; the newest is always frontmost.

A full turn and a half, so it reads as arriving rather than growing.
