/**
 * Full-screen canvas-based confetti renderer. Spawns particles on mount and animates them via `requestAnimationFrame` until all exit the viewport, then fires `onCompleted`. Used internally by `ConfettiBurst`, `ConfettiCannon`, and `FallingConfetti`.
 *
 * All style types can be mixed freely in the same `styles` array. `HTMLCanvasElement` styles (from `createTextStyle`) and `HTMLImageElement` styles are automatically sized to match their dimensions. Image sizes can be overridden via `onCreate` — setting only one dimension (w or h) auto-scales the other to preserve the aspect ratio.
 *
 *  
 *
 * @prop styles {readonly ParticleStyleEntry[]} [COLORS] - Render styles for confetti. Each particle gets a random value. Accepts plain styles (HTML colors, HTMLImageElement, CanvasImageSource) or config objects ({ style, w?, h? }) for per-style sizing. All types can be mixed.
 * @prop particleCount {number} [50] - Number of particles to create.
 * @prop origin {Position} [undefined] - Origin position [x, y]. If omitted, confetti falls from the top.
 * @prop force {number} [15] - Burst velocity. Higher = faster/further. No effect without origin.
 * @prop angle {number} [0] - Burst direction in degrees. Use with spread for directed bursts. No effect without origin.
 * @prop spread {number} [360] - Angular spread in degrees. Use with angle for directed bursts. No effect without origin.
 * @prop onCreate {OnCreateParticle} [undefined] - Callback to override initial particle values at creation time.
 * @prop onUpdate {OnUpdateParticle} [undefined] - Callback called each frame per particle for custom animation logic.
 * @prop onCompleted {() => void} [undefined] - Callback fired when all particles have exited the screen.
