"""Tests for route collision logging (regression: false-positive /embeddings).

The route table handed to ``_log_route_collisions`` is ComfyUI's shared
``PromptServer.instance.routes``, which also contains ComfyUI core routes
(e.g. ``/embeddings``). Those must not be reported as collisions caused by
Majoor (GitHub issue #167 log noise).
