Struct ParseConfig 

pub struct ParseConfig {
    pub emit_source_lines: bool,
    pub implicit_figure: bool,
}

Parser configuration flags.

Threaded through parse_with_config to gate optional parser behaviors that the renderer needs to coordinate with (source-line tracking for preview scroll sync, implicit-figure promotion).

Default = “production preview off” — emit_source_lines: false, implicit_figure: true. The implicit_figure default mirrors today’s always-on behavior of the parser before this config existed; flipping it off is opt-in for the small set of fragment-render call sites that need bare <img> (none today, but the flag exists for symmetry with the legacy transform_events API and the production site_config field).

Fields

emit_source_lines: bool

When true, populates BlockMeta::source_line for top-level blocks. The renderer emits data-source-line="N" on the opening tag for any block whose meta carries Some(N).

Production wires this from process_markdown_file’s emit_source_lines argument (true during preview builds, false during ship-stage publish builds — data-source-line is stripped at ship time anyway, but emitting fewer attrs upstream is cheaper and keeps published HTML clean from earlier stages).

implicit_figure: bool

When true (default), image-only paragraphs promote to Block::Figure via [try_promote_to_figure]. When false, they stay as Block::Paragraph containing one Inline::Image.

Production wires this from site_config.implicit_figure (default true). The flag mirrors the legacy transform_events implicit-figure pass: sites that prefer bare <img> (no <figure> wrap) can opt out.
