- Limit visible weeks to 8 (configurable MAX_VISIBLE_WEEKS) - Add debounced search (300ms delay) to reduce re-renders - Calculate weekTotals in single pass O(rows) instead of O(weeks × rows) - Memoize callbacks with useCallback (handleSort, renderGrowth, handleExportExcel) - Export still includes ALL weeks for complete data
