Scale entrances
A thing that grows from nothing looks like it was fired at you. A thing that settles from 0.95 looks like it was already there.
Popovers, menus and tooltips enter from `scale(0.95)` and opacity 0 with a strong ease-out, with `transform-origin` at the trigger so they grow from the place the person touched. Modals are the exception: they are not anchored to a trigger, so they stay centred. Nothing enters from `scale(0)`.
First render usually has no enter animation at all. The collection on this site is the deliberate exception: its arrival rises cards from sixteen percent of the stage below their places at 94 percent size, because the load is the moment there. On every other page content simply appears, or rises once with the shared curve.
- 0.95 and opacity 0, never 0
- Origin at the trigger for anchored surfaces; centre for modals
- Reduced motion replaces movement with a fade or nothing
