/**
 * EntityAttributes — renders an entity's descriptive content and structured
 * attributes straight from its wiki frontmatter. The generated entity files
 * carry their real content in YAML fields (narrative_summary_*, maneuver_notes,
 * shape, color, roles, countries, …) while the markdown body holds only empty
 * "## Description" headings — so the page must surface the frontmatter.
