The system disk rendered as a checked-and-disabled checkbox, which reads
as "a choice that is locked". It isn't a choice at all — apps fall back
to it whatever happens — so it now carries no control, and is a <div>
rather than a <label> since there is nothing to label. A spacer keeps its
text aligned with the real checkboxes below.
An "Additional drives" divider separates the two kinds of row: above it
is where apps go regardless, below it is what you can opt into. It only
renders when there is something to divide, so the single-disk case is
still one card and a line of text.
Verified both states.
