An empty signature field that a click would sign now carries a small accent tab, with the signature icon and "Sign", inside its top-left corner while the Select tool is active (not while preparing a form). It follows the field click's own checks: the document allows filling, the field isn't read-only, and its widget is shown. The tab drops its label, then itself, on a field too small at the current zoom. Like the validation badges it is screen-only chrome, never written into the file, exports or printing. The label reuses the catalog's "Sign". The tab sits inside the field, so clicking it starts signing that field and hovering it shows the pointing hand. Unit tests cover which fields get a tab (signed, invisible, other-page, unplaced, non-finite and huge rectangles, read-only fields, refused filling, hidden or moved widgets) and the layout; a kittest frame test checks the painted tab, the cursor and the click.
