 - `metrics` when set to `true`, logs timing information via `vim.notify` after each jump-to-fixture and rename operation. Useful for understanding performance in large projects. The jump reports total time and index-build time; the rename reports total, grep, scoping (fixture resolution), and apply time.

-Currently four input methods are supported:
-
-- [`fzf-lua`](https://github.com/ibhagwan/fzf-lua) — used for fixture usages when `preferred_input = 'fzf-lua'`. Results are shown in an fzf picker with preview, and you can open files with Enter, `ctrl-s` (split), `ctrl-v` (vsplit), or `ctrl-t` (tab).

+### fzf-lua
+
+When `preferred_input = 'fzf-lua'` is set and [`fzf-lua`](https://github.com/ibhagwan/fzf-lua) is installed, fixture usages (`PytrizeFixtureUsages`) are displayed in an fzf picker with a built-in previewer. Supported actions:
+
+- `Enter` — open file
+- `ctrl-s` — open in horizontal split
+- `ctrl-v` — open in vertical split
+- `ctrl-t` — open in new tab
+
+If `fzf-lua` is not installed, results fall back to the quickfix list.
