Overview

Represents a named section within text content.

Sections are logical units of text that can be matched and merged independently. For example, in Markdown, sections might be delimited by headings; in plain text, sections might be delimited by comment markers.

This is used for text-based splitting of leaf node content, NOT for AST-level node classification (see SectionTyping for that).

Examples:

A Markdown section

Section.new(
  name: "Installation",
  header: "## Installation\n",
  body: "Install the gem...\n",
  start_line: 10,
  end_line: 25,
  metadata: { heading_level: 2 }
)
