Nitro-V3/tests/mocks/renderer-mock.ts

/**
 * Stub of `@nitrots/nitro-renderer` for Vitest.
 *
 * The real package eagerly loads Pixi v8 + a few hundred Habbo message
 * parsers/composers at module import time, which jsdom cannot host:
 * any `tests/**` file that transitively pulls a renderer symbol throws
 * before a single assertion runs.
 *
 * This module replaces it via `resolve.alias` in `vitest.config.mts`.
 * We provide explicit named exports for the symbols a test currently
 * needs (logger, event dispatcher, doorbell event class); everything
 * else mentioned in the comments below is a generic stub kept just to
 * keep the side-effectful imports happy as `src/api/index.ts` and
 * friends are pulled in transitively by the barrel cascade.
 *
 * Grow this file as new tests require additional symbols. Prefer adding
 * a real (deterministic) stub over wiring `vi.fn()` — it keeps the
 * mocks readable and avoids state bleed between cases.
