An OPEN sign hangs from a nail on two strings and swings toward you and away in 3D. A rotateX pendulum pivoting on the nail, with perspective so the bottom edge grows as it comes near.
Also known as: swinging sign animation, hanging text css, pendulum swing text.

Currently previewing #3b82f6.--txt-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 40px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
