## Summary
- Fix Super+Return keybinding to launch wezterm in sway
- Set fish as default login shell

- Changelog fragment

## Post-merge deployment

+## Software
+
+Managed declaratively via `nixos/ringtail/configuration.nix`. Home-manager handles ringtail-specific sway/waybar config; chezmoi manages cross-platform dotfiles.
+
+- **Desktop:** Sway (Wayland, Catppuccin Macchiato theme) with waybar and wezterm
+- **Browser:** LibreWolf
+- **Gaming:** Steam (library on `/mnt/games`), 8BitDo controller via Steam Input
+- **Audio:** Edifier R1280DBs (Bluetooth), PipeWire
+- **Secrets:** 1Password CLI + GUI (NixOS modules for polkit/setgid integration)
+- **Runtimes:** mise manages Node, Python, Rust, .NET; nix-ld enables dynamically linked binaries
+- **Dotfiles:** `chezmoi init eblume && chezmoi apply`
+
+## Deployment
+
+```fish
+mise run provision-ringtail
+```
+
+This updates `flake.lock` via Dagger, verifies the current commit is pushed to forge, then deploys the exact commit via ansible. If the lockfile changed, it stages the file and exits so you can commit and re-run.
+
+## Maintenance Notes
+
+**1Password:** Desktop app must be running for `op` CLI. Use `$mod+Shift+minus` to send to scratchpad.
+
+**NVIDIA:** Proprietary drivers. Sway launched with `--unsupported-gpu` via greetd.
+
+**No TPM:** `systemd.tpm2.enable = false` prevents 90s boot delay.
+
+**RAM speed:** Running at 3200 MT/s via DOCP 1 (BIOS 8902+).
