`primary_pressed` plus `resp.rect.contains` reads the raw pointer, so
anything floating above the photo — the context menu, a dropdown, a
dialog — also started a guide gesture under it. The gate now asks
`resp.contains_pointer()`, which the hit test keeps honest about
covering widgets; the navigator check stays. Two tests press on a menu
over a line and over an endpoint: nothing is selected, moved or drawn.
