outlay
Virtual Scroll
Ten thousand rows of wrapped text, every row a different height.
outlay lays out the entire 10,001-node list in one
solveLayout call — every row's y and height
below comes from the solver, not from the DOM. Text heights feed in
through the measureContent contract, supplied here by
@chenglou/pretext. Because every position is known before
the first paint, only the rows in view are ever mounted, and there are
no height estimates and no scroll-jump corrections.
Re-answers "height and position of every row" both ways: outlay from the tree, the DOM by mounting a throwaway off-screen copy of all 10,000 rows and forcing a reflow. Nothing on this page changes.
