fix: anchor mobile hero vector to the viewport

Move the mobile hero <img> out of the .vector container (which is intentionally wider than the viewport to bleed the desktop SVG) so the mobile img anchors to .heroVector's full-width edges. Set width: 100vw, left: 0, bottom: 6.25rem so the 402-wide mobile SVG distributes the linework across the full hero at the 402 reference composition.
