simvx.editor.panels._animation_input

_TimelineInput – input routing for the animation panel.

Private sibling helper of :class:~simvx.editor.panels.animation.AnimationPanel. Routes raw mouse/keyboard/scroll events to header/ruler/track regions, owns hit testing and the context-menu interaction model, and delegates all resulting mutations back to the panel. The panel is injected at runtime, so this module never imports it.
