Falling meteors across a dark sky.
Under the hood
High-Velocity Linear Tracing
Meteor paths are drawn rapidly across a canvas utilizing
createLinearGradient to give the tail a fading, trailing glow. The coordinate logic spawns them off-screen with a sharp diagonal angle to ensure they cross the viewport realistically. Related
