Earlier this gate framed image `align` as a 'residual gap' (align dropped, fix
owed in develop). That was a false diagnosis. align round-trips correctly:
`center` is the schema default (emitter omits it, importer restores it), and the
`toBeUndefined()` here reads the CANONICAL form where canonicalize normalizes the
`center` default away symmetrically — not a loss. The real round-trip instability
in this family was the empty-string-vs-absent class (image.alt `absent -> ""`),
fixed parse-side in the converter package on develop (PR #350); this branch
absorbs it via the next develop merge. Comment/title only — assertions unchanged.
