-Niri and Kitty bindings are unchanged. Syntax and action names were checked against

-Verification: repository formatting, rendered TOML parsing, flake evaluation,

+Niri and Kitty bindings are unchanged. Direct number bindings are removed because
+the user finds them unergonomic; built-in prefix shortcuts remain available.

+Use one space per project or worktree, tabs for different activities, and panes
+for tools needed together. Start Neovim in a shell, split right with Ctrl+Alt+V
+for an agent shell, and optionally split that pane down with Ctrl+Alt+Minus for
+tests or a server. Choose and launch the agent manually. No preset is installed.
+Ctrl+Alt+Shift+G opens lazygit at 90% width/height in the focused pane's working
+directory. Quit lazygit to return; the popup owns input until its command exits.
+
+Tabs now open immediately with generated names; rename them only when useful.
+New spaces already skip naming, and new panes inherit the current directory by
+default. Workspace-close confirmation remains enabled to protect running work.
+Direct resizing, previous/next agent navigation, last-pane switching, copy mode,
+and Neovim scrollback access avoid extra navigation or mode-entry steps.
+No documented native setting or CLI action opens Goto directly in search mode;
+that limitation remains under the configuration-only constraint. No input macros,
+plugins, or package patches are added.
+
+After activating Nix, reload Herdr with Ctrl+B then Shift+R; subsequent reloads
+can use Ctrl+Alt+Shift+R. The expanded shortcuts require interactive verification
+through Kitty, including popup working directory, pane swapping/resizing, and
+scrollback opening. The earlier bindings were reported working by the user.
+Verification (2026-09-10): formatting, flake evaluation, Polaris and Zenith no-link
+system builds, and whitespace checks passed. Both hosts generate identical Herdr
+TOML, accepted by installed Herdr 0.9.0's `config check`. No activation or live
+Herdr session changes were performed.
+The earlier activation installed the Herdr config and preserved `config.toml.bak`,
+but Home Manager later timed out (below).
