// Career Workspace foundation, Phase F2 (career-workspace-implementation-roadmap.md). A CvVariant
// is a durable, named lens on the career profile -- unlike TailoredCvDraft, it is not owned by a
// job; TailoredApplication is the reference that links a variant to a job, so the same variant can
// be reused across applications and a job can be deleted without losing the variant.
//
// This phase dual-writes from the existing TailoredCvDraft save paths (same pattern as
// CareerProfile in Phase F1): every draft save also upserts the job's CvVariant, appends a
// CvVersion snapshot, and ensures a TailoredApplication link. TailoredCvDraft remains the
// authoritative row every existing read path uses.
