Trade moves between its pages without a reload (plan T11): openvibe-shared v2.2.0 boost swaps <main> styles-first with the shared transition, prefetching on intent, and does a normal load across a deploy (the ov-boost marker carries the release). The navbar's sign-in returns to the current page. test/layout-boost.test.js pins the marker, the boost tag and the login template.
