Paste Images from Clipboard into Text Blocks

Feature Request: Paste Screenshots (Images from Clipboard) into Text Blocks

Problem:

Currently, when a user copies an image or takes a screenshot (e.g. with Cmd + Shift + Ctrl + 4 on macOS), pasting it into a text block doesn't insert the image.
This breaks expected behavior and forces workarounds like saving the image to disk first, then uploading manually.

Proposed Solution:

• On paste, insert the image block.

• Upload and store the image in context folder, then embed it in the page.
