Unsafe cast may silently produce "undefined" in output.

(block.content as StyledText<any>[]).map((item) => item.text) — if block.content ever contains a non-StyledText item (e.g., a Link, which has no top-level .text), then item.text is undefined, and .join("") silently emits the string "undefined" into the exported code block text.

The comment acknowledges code blocks should only contain StyledText, but the cast provides no runtime guard.

🛡️ Proposed defensive fix

-    const textContent = (block.content as StyledText<any>[])
-      .map((item) => item.text)
-      .join("");
+    const textContent = (block.content as StyledText<any>[])
+      .filter((item) => item.type === "text")
+      .map((item) => item.text)
+      .join("");

122, The current unsafe cast of block.content to StyledText<any>[] may produce
"undefined" if non-StyledText items (e.g., Link) appear; update the computation
of textContent to guard at runtime by treating block.content as an array of
unknown, filter or flatMap items that actually have a string .text property
(using a type guard or typeof check) before mapping and joining, and ensure
non-text items are skipped or replaced with a safe fallback (empty string) so
textContent never contains "undefined" while keeping references to block.content
and StyledText intact.
