fix(apologetik/contra): scope answer-rail width:max-content to >=760px

The answer-rail had width:max-content with a wider max-width override
gated behind @media (min-width:760px). The width:max-content sat
outside the media query, so on mobile it inflated the rail's max-content
contribution to .arg-body's 1fr grid track. The track expanded past the
viewport (max-width:100% can't clamp during cyclic track sizing), making
.arg-body and its h2/text appear to overflow horizontally.

Move width:max-content inside the >=760px block so the desktop break-out
behaviour stays, while mobile falls back to default flex-wrap within
the column.
