(2024-08-04) Simplified-tldraw-proxy idea

I want some a variation of tldraw that lets me

• have the code for a diagram as a block within a CommonMark/WikiFlux page
• renders "preview" in-page, click to pop-up/out to dedicated-image editable page
• can edit document and save back into page-block
• can use double-brackets in text-in-node, and have it render appropriate local-link
  • and WikiGraph scraper can associate those links with the page
• hmm, do I need/want a simplified diagram/markup?
  • having it the markup be fairly readable without the diagram
  • be able to make minor edits right in the markup
  • see Jun'2024 toot showing how complicated the tldraw code is
  • but maybe this doesn't matter
