Flat list + sticky summary
Variant 1 of 3 · regenerated after gate feedback
↻ Regenerated. The first pass put 4 category tabs here — essentially the Filter pattern the research rejected. Fed back: "don't reintroduce category multiplication." This direction drops category nav entirely.
What changed
No tabs, no filter chips. One flat list; each item carries an inline Replace / Keep toggle. A sticky summary band stays pinned at the bottom and updates live as you toggle — the count can never go off-screen.
What was kept
Decision language (Replace / Keep), plain-language can't-swap (locked rows), and a count that's always visible.

No way to jump to a category — on a long order, finding one item means scrolling the whole list. That's the exact problem tabs solved, so this trades fast-locate for zero-nav simplicity.
