+- Reduce large-table selection latency by deriving reactive table selection from editor selectors, keeping selected-cell DOM sync at the table root, and avoiding plugin-store writes on every `set_selection`.

-## Conclusion
-
-- The `40 x 40` remount benchmark is still in the high-cost range, with a mean of ~`841 ms`.
-- The `40 x 40` input latency mean is ~`41 ms`, median ~`39 ms`, well below the `100+ ms` threshold where noticeable lag occurs.
-- This snapshot is better suited for tracking large-table input performance; if the focus shifts to resize/hover interactions, a separate drag/hover profiling session is recommended.
-
-## Interpretation Notes
-
-- `Initial render`, `Re-render count`, `Last render`, and `Avg render / Median / P95` come from the left-side Metrics panel.
-- `Benchmark Results` are the remount benchmark statistics.
-- `Input Latency` results do not auto-clear when switching presets or clicking `Generate Table`; re-run after changing configuration.
