## What it is
Animatic is a lightweight (7k gzipped) JavaScript library for CSS animations that combines CSS transforms with JavaScript control. It supports animating many objects simultaneously, with start/stop/cancel control, timeline sequencing, and elementary physics simulation (mass and viscosity) for lifelike motion.

## Use cases
- animate DOM elements with CSS transforms and full JS control
- create start/stop/cancelable animations instead of pure CSS transitions
- generate pure CSS keyframe animations from time-based durations
- simulate realistic motion with mass and viscosity physics
- sequence and run parallel or infinite animations
- build event-based animation flows in the browser

## When to choose
- you need programmatic control over CSS animations (start, stop, cancel)
- you want physics-based lifelike animation with a tiny footprint
- you prefer thinking in durations and delays rather than keyframe percentages
- you need to animate many elements simultaneously with transforms

## When to avoid
- you need modern Web Animations API features or broad ecosystem support
- you require React/Vue component-level animation integration
- the project appears to be in maintenance mode with limited updates
- you need complex parallel pure-CSS generated animations (a documented limitation)
