Since the signature became a verbatim, non-editable atom (#476), there was no way to edit it in the composer at all (#822) - the styling guarantee silently cost the editability #329 had established. Keep the atom as the default so branded signatures still survive 1:1, and let an explicit gesture opt out: double-clicking the block dissolves it into regular editable content at the same position. Double-clicks that land on a link are ignored (the click is working the link), and Enter on the selected block keeps ProseMirror's default create-paragraph-after behaviour. Faithfulness of the dissolved signature: - Leaf <div> lines become paragraphs; only vertical margins the line does not declare are reset to 0 (how a div actually renders), so explicit spacing and indents survive. Divs carrying hr/pre and other non-line blocks are left to the schema parse. - Inherited styles (font, color, ...) on wrapper divs - which have no schema node and would be dropped - are hoisted onto the generated line paragraphs, the line's own declarations winning. - The content is parsed as a CLOSED document via the schema DOMParser and spliced in with one transaction; insertContentAt fits an open slice, which can split text runs at hard breaks and turned <br>-lined signatures into one spaced paragraph per line. The bracketing data-signature-block markers live outside the atom and stay put, so the identity-switch splice and the send path's already-embedded detection keep working on unlocked content, and switching identities re-embeds a fresh locked block. Undo restores the atom. A translated tooltip on the block makes the gesture discoverable.
