    ℹ️ <strong>How this works:</strong> Planning is for what you <em>haven't</em> memorized yet.
    Marking a plan <strong>Done</strong> automatically creates (or links to) a record in
    <a href="{{ url_for('memorization') }}">Entry Form</a> — you don't need to enter it there separately.
    Already memorized something and want to revisit or strengthen it? Use
    <a href="{{ url_for('revision_log') }}">Revision</a> instead of planning it again here.
