/**
 * Backend-neutral base class for renderer batchers.
 *
 * A batcher accumulates vertices into a CPU staging buffer and turns them
 * into GPU work in batches — one draw call for many shapes/sprites. This
 * class defines the lifecycle contract shared by every backend:
 *
 * - `init(renderer, settings)` — build (or rebuild after a context/device
 *   loss) the batcher's GPU-facing state; called by the constructor
 * - `bind()` / `unbind()` — the renderer switches the active batcher
 * - `flush()` — turn the pending vertices into GPU work
 * - `reset()` — drop transient state (game reset / context restore)
 * - `destroy()` — release every GPU resource the batcher owns
 *
 * Custom batchers extend the class matching the renderer they target —
 * {@link WebGLBatcher} for the WebGL renderer, `WebGPUBatcher` for the
 * WebGPU renderer — and are registered through `renderer.addBatcher()`,
 * which accepts any Batcher subclass.
 * @category Rendering
