 *   `getCollection<T>()`.
 * - `body`: markdown body for `.md` / `.mdx` entries; empty string for
 *   `.tsx` entries (TSX has no separate markdown body).
 * - `module_specifier`: stable specifier addressing the compiled module
 *   (`mdx://collection/slug#hash` / `tsx://collection/slug#hash`). The
 *   bridge resolver matches either the full-with-hash form or the
 *   no-hash form `mdx://collection/slug`.
 * - `rel_path`: path relative to the collection root, normalized to
 *   forward slashes so JSON is platform-stable.
 * - `render_metadata`: present only when the build ran with
 *   `emitRenderArtifacts` on, and only for markdown entries. The Rust
 *   side skips the field entirely when the feature is off, so an
 *   unflagged build's snapshot bytes are unchanged.
