Milestone3UITests.testPerPagePrint (Tests/ICCeryUITests/Milestone3UITests.swift:242-269) is the only UI test that must scroll stage 2 before pressing a Print button — btnPrintPage-0 sits at the window's bottom edge (originally #132).
Its helper scrollStage2UntilHittable (Milestone3UITests.swift:130-168) scrolls by synthesizing press(forDuration:thenDragTo:) finger-drags on the galleryPage-0 cell, falling back to the stage-2 scroll view. A macOS ScrollView/LazyVGrid does not scroll in response to a click-drag — observed runs show ~3 drag attempts while the gallery frame never moves, so the loop burns its 20 s budget and the button may never become hittable.
The helper's comment claims a synthesized scroll wheel is "inert on this LazyVGrid". That assumption is backwards: the finger drag is the inert gesture on macOS, and the scroll-wheel gesture is the mechanism the platform actually supports — which was also the fix originally proposed in #132.
Proposed Fix
Replace both press(forDuration:thenDragTo:) calls in scrollStage2UntilHittable with the XCUI scroll-wheel gesture — scroll(byDeltaX:deltaY:) on a coordinate inside app.scrollViews["stage-2"] (verify deltaY sign so content moves up, off the Dock zone).
Keep the poll-until-hittable loop, the windowBottom - 80 Dock-zone guard, and the "never coordinate-click a stale frame" contract unchanged.
Update the helper's doc comment to drop the "scroll wheel is inert" claim.
Sweep: thenDragTo/press(forDuration exists only in Milestone3UITests.swift — no other test needs changing.
Acceptance Criteria
scrollStage2UntilHittable uses scroll(byDeltaX:deltaY:) (or the element-level scroll API); no press(forDuration:thenDragTo:) remains.
testPerPagePrint passes with btnPrintPage-0 becoming hittable via the scroll gesture.

`Milestone3UITests.testPerPagePrint` (`Tests/ICCeryUITests/Milestone3UITests.swift:242-269`) is the only UI test that must scroll stage 2 before pressing a Print button — `btnPrintPage-0` sits at the window's bottom edge (originally #132).

A macOS `ScrollView`/`LazyVGrid` does not scroll in response to a click-drag — observed runs show ~3 drag attempts while the gallery frame never moves, so the loop burns its 20 s budget and the button may never become hittable.
