The page arrived with this content already in the HTML, and the HTML is the only copy of it. The queries parsed their starting state back out of the server-rendered markup, and every update has been a surgical patch against the server-rendered rows. The prices show the other half of the convention. A cell renders $1,250 while the machine value 1250 rides the row's data-seed attribute, which wins the merge at adoption. The inventory total is the proof, computed from those seeded numbers before the first fetch ever runs, and it matches the server's own arithmetic from first paint.
