Search moves between its pages without a reload (plan T11): openvibe-shared v2.2.0 boost swaps <main> styles-first with the shared transition and does a normal load across a deploy (the ov-boost marker carries the release); page scripts that wire <main> also run on ov:boost:load. Tests pin the marker and the boost tag (verified).
