React.memoto theBatchItemcomponent to prevent unnecessary re-renders when pagination or list state changes.<QRCode>component so it only renders when the row is visible on the current page (isVisible). If hidden, it renders an empty<div>with the same dimensions (90x90)..jules/bolt.mdabout optimizing DOM-dependent tools.🎯 Why:
<QRCode>SVG for every single row in the dataset, even if the row was hidden by CSS (not on the current pagination page). This caused significant memory and CPU overhead.ReactHTMLTableToExcellibrary relies on reading the DOM structure to export data, we cannot completely unmount hidden rows.

<QRCode>SVG generation cycles.🔬 Measurement:
