amvcp-anim-perf

What problem does it solve?

This Skill prevents expensive animation work from wasting CPU by pausing infinite loops off-screen and deferring non-critical initialization until the browser is idle.

Core Features & Use Cases

• Off-screen loop pause (AN-11): Automatically pauses infinite ambient loop elements when they leave the viewport.
• Idle-deferred initialization (AN-11): Splits init into an immediate Tier 1 that gates visible content and a deferred Tier 2 that wires polish/perf logic using requestIdleCallback (with fallback).
• Delta-time rAF loop primitive (AN-12): Provides a reusable createLoop(update, render) pattern with capped dt and safe start/stop semantics for canvas/game-loop consumers.
• Dynamic content re-scanning: Refreshes loop and runtime wiring after subtree insertions so new elements participate correctly.

Quick Start

Use the amvcp-anim-perf primitives to budget animation CPU by enabling off-screen loop pausing and wiring any custom rAF/canvas loop via the delta-time createLoop(update, render) pattern.
