Subject: [PATCH] fix: editor title wraps to multiple lines instead of overflow
 hidden

Converted the title field from <input> to <textarea> with auto-resize
so long titles wrap naturally onto multiple lines. The textarea grows
to fit content (via scrollHeight) and shrinks back when text is
removed. Added resize:none and overflow:hidden in CSS to suppress
the drag handle and scrollbar.
