textarea-autosize-swell
An autosize textarea that grows like dough proofing instead of reflowing like a spreadsheet cell: ordinary typing raises it line by line with a soft 180ms swell, a large paste breathes open over 400ms in one continuous motion instead of popping, and deleting text back down is slower still (320ms) so the surface never snaps under the cursor.
