Time source for the animation system.
By default this is the wall clock (System.system_time(:millisecond)), so
live rendering is unaffected. Offline renderers (the video render target) can
freeze/1 it to a fixed virtual time, making every captured frame
deterministic regardless of how long rasterization actually takes.
Both the per-frame "now" (Raxol.Animation.AnimationProcessor) and an
animation's start_time (Raxol.Animation.Lifecycle) read through here, so a
frozen clock keeps interpolation coherent across the two.
The freeze is global to the BEAM node. Freeze only while driving a dedicated, offline render; do not freeze while serving live animated UIs on the same node.
Summary
Functions
Pin animation time to ms until unfreeze/0.
