1. Added `text-sm` to the container wrapper (line 190)
2. Removed redundant `text-sm` from the `paragraph` theme (line 102)
3. Removed redundant `text-sm` from the `code` theme (line 129)
Now all markdown elements in the WYSIWYG editor will inherit `text-sm` from the container, ensuring consistent font sizing for paragraphs, lists, blockquotes, and other elements.
