Auto-close (markIncomplete, on in streaming parses) writes the stage of the innermost block component it had to close on its closer: ':: <!-- auto-close: name|props|content -->'. Block closers now accept a trailing HTML comment; the components plugin reads the auto-close one into $.ac on the component and, for 'content', on its last slot. Also: close a code fence still open inside a component before the component closer, keep a typed '::' closer under dropTrailingOpeners, and add a Streaming toggle to the /play options.

Apply Streaming to generated-content previews.
The completion watcher calls parseMarkdown and writes a non-streaming result directly to document.value. The debounced updatePreview and final onFinish parse use Streaming, but intermediate completion updates can display unstamped content.
Create the parser in the completion watcher and pass the selected Streaming option.

Classify fenced YAML props as props.
For ::alert\n```yaml [props]\ntype: x, the scanner leaves stage as content. The components plugin accepts that fence as a props block, so streaming emits the wrong $.ac value. Track supported fenced props openers and change the stage to content when their fence closes.

Preserve indented component closers.
If a nested component ends with :: and no newline, i points after the indentation. This condition fails, and dropTrailingOpeners removes the typed closer. The scanner then treats the component as open and adds an incomplete-stage marker. Accept whitespace between the line start and the colon run.

Summary
While streaming, the innermost block component that is still being typed now carries
$.ac, so renderers can show a placeholder instead of flashing a half-typed component.$.acname::alertprops{...}props or a YAML props block::alert{type="incontent::alert\nsome textWith
content, the component's last slot (template) is stamped too. Parents, finished components and non-streaming parses have no$.ac.How it works
markIncompleteoption, whichstreaming: trueturns on. Only the closer of the innermost open component gets a comment::: <!-- note -->), which is dropped. Anauto-close: <stage>comment is read intometa.acon the component's open token, and on its last slot forcontent.meta.acinto$.ac.There's no separate pass and no extra state passed between auto-close and the parser, and it doesn't depend on the
