📝 Walkthrough

Summary

• Added JSDoc documentation to public Markdown utility functions.
• Documented parameters, return values, and usage examples.
• Added examples for content handling, mark management, blank lines, and Markdown blocks.

Walkthrough

The PR expands JSDoc for eight Markdown utilities. It adds parameter and return descriptions plus examples for content handling, block formatting, blank-line conversion, and mark lifecycle behavior. No implementation behavior or public declarations changed.

Changes

Markdown utility documentation

Layer / File(s)	Summary
Content and block utility documentation packages/markdown/src/utils/assumeContentType.ts, packages/markdown/src/utils/extractAbsorbedBlankLines.ts, packages/markdown/src/utils/wrapInMarkdownBlock.ts	Added examples for JSON inference, string passthrough, blank-line token conversion, and Markdown block formatting.
Mark lifecycle documentation packages/markdown/src/utils/closeMarksBeforeNode.ts, packages/markdown/src/utils/findMarksToClose.ts, packages/markdown/src/utils/findMarksToCloseAtEnd.ts, packages/markdown/src/utils/findMarksToOpen.ts, packages/markdown/src/utils/reopenMarksAfterNode.ts	Documented mark inputs, outputs, opening, closing, reopening, and LIFO ordering examples.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 64422

The PR adds examples to markdown utility documentation, but two APIs still do not explain how they mutate activeMarks. This may mildly mislead readers of the API docs without affecting runtime behavior, so the PR is mergeable with explicit owner awareness or a small documentation follow-up.
