"""A caller's own binary is never replaced -- but it should still be checked.

A managed install below the floor gets upgraded by pkgman. `executable_path`
deliberately bypasses that, which leaves one pairing nothing checks: an old
build driven by Playwright >= 1.61, whose viewport fields the older Juggler
schema rejects. Without this the user sees a bare "Protocol error
(Browser.setDefaultViewport)" and nothing naming the cause.

It warns rather than raises on purpose: camoufox defaults to no_viewport when
it spoofs window dimensions, so the default path works on an old build. Only an
explicit viewport breaks, so refusing to launch would break working setups.
