Struct HeadingSpan 

pub struct HeadingSpan {
    pub level: u8,
    pub title: String,
    pub start_offset: usize,
    pub end_offset: usize,
}

A single H3–H6 heading span recorded under one H2 section. Byte offsets reference the raw section content (the string stored in Entity.sections[key]). Spans are stored flat — level skips (H2 → H4 without H3) are tolerated and ancestry is resolved at query time via offset containment, not by inserting virtual intermediate spans.

Fields

level: u8

Markdown heading level: 3, 4, 5, or 6.

title: String

Heading title (trimmed, no # prefix).

start_offset: usize

Byte offset into the section content where this heading starts (the # character position).

end_offset: usize

Byte offset into the section content where this heading’s scope ends — either the start of the next heading with the same or lower level, or the end of the section.
