"""Under ``gateway.multiplex_profiles`` one process serves every profile; each routed turn runs with
a context-local HERMES_HOME override. Tool-side state resolved once at import, or cached in a
single unkeyed slot, would hand the launch profile's paths/limits to every other profile.

Each test warms the site under profile A, flips the override to profile B with different
config, and asserts B sees its own values (real temp homes, real config.yaml, no mocks).
