A live layout-profiler overlay panel. Renders as an
absolutely-positioned <Box> anchored to a corner — it does not
reflow the host app. Shows the latest LayoutTrace, a recent-cost
sparkline, and cumulative per-path totals.
The panel is a fixed PANEL_WIDTH columns wide and self-sizes its
height from the content rows it renders.
Caveat: being in the host's render tree, the panel's own nodes are
counted in the traces it reports — absolute counts run slightly
high. The path classification is unaffected.
