Method and worked example
Reference blocks separated by blank lines are kept intact. When no blank lines exist, each nonempty line is treated as one reference. A separate normalized key is compared with a stable Intl.Collator configuration; only block order changes.
Smith, Doe, and Brown references are returned as Brown, Doe, Smith. Multi-line blocks move as whole units, and tied keys retain their original order.
Scope and limitations
This alphabetizes visible reference text; it does not guarantee APA, MLA, Chicago, or another style’s special semantic ordering rules.
Review the output before using it in academic, publishing, or identity workflows.
