The mobile contact linework is loading=lazy and only resolved when scrolled into view. Wait for it to finish loading before the geometry assertions read its bounding rect, matching the pattern already used for the Our Work desktop vector.
Replace the clip-path composition of the desktop SVG with a real <img> that references the artist-supplied mobile-work-vector.svg. Drop the CSS-layer trick and the ::before/::after background pieces; the new mobile SVG already covers the composition. Update the linework composition test to assert against the new <img>.
Render mobile-contact-vector.svg alongside the existing contact linework. CSS hides the desktop SVG and shows the mobile <img> at <=767px so the new 342x187 composition fills the card width. Update the geometry test to assert the new linework ratio (342/187) and the snapshot.
Swap pullquote-mobile-linework.png for the artist-supplied mobile-pullquote-vector.svg at the existing pull-quote__vector--mobile slot. Update the visual snapshots to match the new artwork.
