* Fork of graph2d-react `tinymce/graph2d-plugin.js` (keep in sync on package upgrades).
* Adds handling for { mceAction: 'close' } so GraphEditorStandalone "Close" dismisses the URL dialog.
*
* TinyMCE 6 plugin: Insert / edit Graph 2D drawings via a URL dialog.
*
* Setup:
* 1. Install: npm install tinymce
* 2. Load this script after TinyMCE (e.g. as a plugin script or import).
* 3. Add to editor init: plugins: '... graph2d', toolbar: '... graph2d'
* 4. Set graph editor URL: graph2d_url: 'https://yoursite.com/graph-editor'
* Optional: graph2d_size_percent (e.g. 90 = 90% of viewport), or graph2d_width, graph2d_height (dialog size in px).
*
* The page at graph2d_url must:
* - Post { mceAction: 'graph2d-ready' } when loaded (so we can send initial data).
* - Accept postMessage { type: 'graph2d-init', data: encodedString } to import existing graph.
* - Post { mceAction: 'graph2d-insert', data: encodedString } when user clicks Insert, then { mceAction: 'close' }.
*
* Using in another project: You must host the graph editor page in your app and set graph2d_url
* to its full URL (e.g. window.location.origin + '/graph-editor'). Otherwise the dialog will open blank.
* See docs/TINYMCE_GRAPH2D_PLUGIN.md §9.
