tempus

merges every requestAnimationFrame call into a single loop to cut per-frame overhead

run animations in an explicit order each frame instead of registration order

throttle callbacks to a target FPS (absolute like 30, or relative like '50%') independent of the display refresh

every callback gets state.budget() (ms left this frame) to gracefully skip or chunk work

play(), pause() and restart() the whole loop at once

patch() absorbs every native requestAnimationFrame (including third-party and minified loops) into the shared loop

tempus/profiler draws a real-time timeline of how each callback fills the frame budget

Tempus.inspect() exposes per-callback timing for added and patched loops alike
