Each field was a row of a four-column table: name, lock, value and the
site's current value. On a narrow screen the columns squeezed the
inputs down to a few characters wide.
Each field is now a card with its name and lock on one line and the
input below at full width. The site's value shows only when it
differs, folded behind a line that opens on tap, instead of always
taking its own column. The lock is a labelled toggle instead of a
bare checkbox, and Save stays disabled until something changes.
On a wide screen, the label sits beside the field instead of above
it, and a single-line input no longer stretches to fill the card.
