Description

There are a number of issues with the rocket animation shown on the Congrats page. In no specific order,

  • The page take up between 10 and 30% of my CPU to render the animations on a MacBook Pro from 2015.
  • Firefox has a different animation from other browsers, where the rocket exhaust__line extends further than it should.
  • For other browsers (tested in Chrome and Safari on macOS), the smoke is cropped to the sides because of root-level SVGs being overflow: hidden.
  • The animation doesn’t respect [prefers-reduced-motion: reduce](​https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion) (more of an enhancement).
