Rive Animator

A .riv is a small interactive program, not a picture: artboards, timelines, and a state machine deciding which timeline plays and when. The failures that cost time never raise an error:

• The file is not what was asked for. It builds and loads, with a state that has no way out, an input nothing reads, a pose it snaps to, a loop that pops at its seam, or an angle in degrees.
• The host wires it wrong. An input name off by one letter, the wrong state machine, a canvas at 0×0. The runtime plays the first animation and stays silent.
• It works and feels dead. Everything moves in sync, every pose stops dead, colours swap, nothing breathes between actions.

Never type a state machine or input name from memory, and never claim it works without having rendered and interacted with it.
