- product card descriptions and toggle card content both use `<KoeingBasicHtmlTextarea>` which is a stripped down Koenig editor with basic formatting support where heading sections are not expected
- when pasting into or updating the content in `<KoeingBasicHtmlTextarea>`, convert any headings, blockquotes, or other markerable section types to standard paragraphs so the content formatting matches what is possible through the editing interface
no issue
- text-replacement-input text expansions were customised to not use backticks for code and to have special format handling for `{}`
- switched to it's own set of text expansions that cover the standard expansions used in the main editor except for headings and card replacements
no issue
- the component was still using the text-replacement component's key commands which didn't include code formatting because code in text-replacement component is re-purposed for replacement string highlights

- Because we allow <br> in the editor, the editor placeholder was remaining when editing (<p><br></p>). This clean the editor placeholder.

- This only solves partially the line-returns being eaten by the editor. When editing a card with a line return, it will be removed.
