Elements are now pass-scoped value handles: tests that read bounds after a frame bind a ui.Handle. pixel tells frames apart by the build pass's root, since the Tester clock no longer moves on its own. Fix the regressions the upgrade brought: - Clipboard reads in input handlers go through c.Services(). - MyGo notes an overlay's opener after building it, so AutoFocus inside lost it; pixel.AutoFocus focuses through a Handle, and archtest bans the raw call. Dialogs hand the focus back again. - Elements around a press stay hovered: Tooltip tells a press-given focus by focus arriving under the pointer. - The web host moves the Tester clock with real time, at most 500 ms a call, and gives components the real clock. The gallery's source index also accepts CRLF checkouts. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
