 * Row-measurement for the table virtualizers. TanStack's default reads
 * `offsetHeight` when called without a ResizeObserver entry — i.e. on row
 * mount mid-commit, forcing a reflow per new row while scrolling. That read is
 * redundant: `observe()` delivers an initial `borderBoxSize` entry the same
 * frame, post-layout. So entry-less we return the assumed size (cache/estimate)
 * — a no-op — and let the observer entry supply the real one.
