 * `compareOdf` is the public entry: it takes two `content.xml` STRINGS, parses each exactly once
 * internally (no DOM Element crosses the package boundary, no public DOM accessor on
 * `OdfDocument`), diffs the body paragraphs, emits ODF tracked-changes into the revised DOM, and
 * returns the redline `content.xml` plus edit stats. Diff and emit live in separate modules so the
 * diff is testable without round-tripping a `.odt`.
 *
 * Granularity: aligned-but-differing paragraph pairs above `similarityThreshold` are diffed
 * WITHIN the paragraph (token-level) and emitted as inline tracked changes; below-threshold
 * replacements and pure adds/removes keep the Slice-1 whole-paragraph shapes.
