+## Context
+
+The desktop already uses Home Manager modules under `modules/home-manager` and keeps Hyprland keybinds in `modules/home-manager/hyprland/default.nix`. The new capability is a small user-session workflow, not a daemon: select a region with `slurp`, record it with the Wayland-native `wf-recorder`, encode the result with `ffmpeg`, and publish the finished file with `wl-copy`.
+
+The same Hyprland bind must start and stop the workflow. The first invocation needs to remain alive while recording; a later invocation needs a stable way to find and signal that process. The implementation also needs to avoid leaving partial files in the screenshots directory when selection is cancelled or encoding fails.
+
+## Goals / Non-Goals
+
+**Goals:**
+
+- Encapsulate packages, script, option, output directory, and runtime state in `modules/home-manager/gif-recorder`.
+- Use a single toggle command suitable for a Hyprland `bind`.
+- Select a rectangular region interactively through `slurp`.
+- Save optimized GIF output in `~/Pictures/Screenshots` and copy it as `image/gif` with `wl-copy`.
+- Keep host wiring minimal: import/enable in `hosts/jpporta-nixos/home.nix`, bind in the existing Hyprland module.
+
+**Non-Goals:**
+
+- Full-screen or window recording modes.
+- A recording history, notification UI, configurable encoder settings, or a separate stop bind.
+- A new service or background daemon.
+- Changes to the existing screenshot flow.
+
+## Decisions
+
+### D1. One shell script owns the toggle state
+
+The module installs one `gif-recorder` executable and uses a runtime-directory state file containing the active script PID. If the state file names a live process, a new invocation sends it `SIGINT`; otherwise it runs `slurp` and starts a recording. This keeps the bind to one command and avoids adding a service or IPC layer.
+
+**Alternative:** use separate start/stop scripts or a systemd user service. Rejected because they add commands and lifecycle machinery for one short-lived action.
+
+### D2. Use `wf-recorder`, `slurp`, `ffmpeg`, and `wl-copy`
+
+These tools are small, composable Wayland utilities already suited to the requested flow. `wf-recorder` receives the geometry selected by `slurp`; `ffmpeg` handles palette generation and GIF encoding; `wl-copy --type image/gif` makes the resulting file available to Wayland clipboard consumers.
+
+**Alternative:** OBS or a screenshot/GIF application. Rejected because a GUI recorder is heavier than the requested Hyprshot-like interaction.
+
+### D3. Encode through a temporary video file
+
+Recording first to a temporary Matroska file keeps the output atomic: the final timestamped GIF is moved into `~/Pictures/Screenshots` only after `ffmpeg` succeeds. The encoder uses a palette-generation filter and a bounded frame rate/width to avoid the worst GIF size and color-quality problems without introducing configuration options.
+
+**Alternative:** record directly to GIF. Rejected because palette generation and interruption handling are worse, and `wf-recorder` is designed primarily for video output.
+
+### D4. Store state under `XDG_RUNTIME_DIR`
+
+The state file belongs in `${XDG_RUNTIME_DIR:-/tmp}` and is removed on normal completion or cancellation. It is session-local and avoids polluting the home directory with a lock file.
+
+## Risks / Trade-offs
+
+- [GIFs are inherently large and limited to 256 colors] -> Cap output at a modest frame rate and width; keep the original temporary recording out of the screenshots directory.
+- [A crashed process can leave a stale state file] -> Check whether the recorded PID is alive before treating the workflow as active, and remove stale state before starting.
+- [Clipboard consumers differ in GIF support] -> Publish with the explicit `image/gif` MIME type; the saved file remains the fallback when a consumer cannot paste animated images.
+- [The second bind may be pressed while region selection is active] -> Keep the controlling script PID in the state file before invoking `slurp`, and handle interruption by cleaning up without creating output.
+
+## Migration Plan
+
+1. Apply the Home Manager configuration for `jpporta-nixos`.
+2. Press the new Hyprland bind and select a region; press it again to stop and wait for encoding.
+3. Verify the GIF in `~/Pictures/Screenshots` and paste it into a GIF-capable Wayland application.
+4. Roll back by disabling/removing the module import and bind; no persistent data migration is required, and existing GIF files are left untouched.
+
+## Open Questions
+
+- The exact key combination should follow the existing screenshot bind convention in the Hyprland module; implementation should reuse that convention rather than introduce a new modifier scheme.

+## Why
+
+The Hyprland desktop has a screenshot flow but no equally convenient way to capture a short animated region of the screen. A Wayland-native GIF recorder should let the user select a region, press the same bind to stop, and receive the finished GIF in `~/Pictures/Screenshots` and on the clipboard.
+
+## What Changes
+
+- Add a new Home Manager module, `modules/home-manager/gif-recorder`, with a single enable option.
+- Provide a Wayland-native recording script using `wf-recorder` and `slurp` to select and record a screen region.
+- Toggle recording with one Hyprland bind: the first press starts region selection/recording and the next press stops it.
+- Convert the recording to an optimized GIF after stopping.
+- Save completed GIFs under `~/Pictures/Screenshots` with timestamped filenames.
+- Copy the completed GIF to the Wayland clipboard for immediate pasting.
+- Enable the module from `hosts/jpporta-nixos/home.nix` and add only the required bind in the existing Hyprland Home Manager module.
+
+## Capabilities
+
+### New Capabilities
+
+- `gif-recorder`: Select, toggle-record, save, and clipboard-copy short Wayland screen-region GIFs.
+
+### Modified Capabilities
+
+- None.
+
+## Impact
+
+- New Home Manager module and user-facing recording script.
+- Existing `modules/home-manager/hyprland/default.nix` gains the toggle bind.
+- `hosts/jpporta-nixos/home.nix` imports and enables the module.
+- Adds the runtime packages `wf-recorder`, `slurp`, `ffmpeg`, and a Wayland clipboard utility through the module.
+- Creates `~/Pictures/Screenshots` when a recording is completed; existing screenshot behavior remains unchanged.

+
+#### Scenario: Successful finalization
+- **WHEN** an active recording is stopped and encoding succeeds
+- **THEN** the recorder creates the screenshots directory if needed and stores one completed GIF there
+
+#### Scenario: Failed finalization
+- **WHEN** recording or GIF encoding fails
+- **THEN** the recorder does not publish a partial GIF as a completed screenshot and removes temporary recording data

+### Requirement: Completed recordings are copied to the Wayland clipboard

+
+#### Scenario: Clipboard copy succeeds

+- **THEN** the recorder publishes that GIF to the clipboard as `image/gif`
+
+#### Scenario: Clipboard copy is unavailable
+- **WHEN** a GIF is successfully written but clipboard publication fails
+- **THEN** the recorder preserves the GIF in `~/Pictures/Screenshots` and exits without deleting it
+
+### Requirement: Home Manager integration is opt-in
+The feature SHALL be exposed as a Home Manager module with an enable option, and enabling it SHALL install all required runtime tools and the recorder executable.
+
+#### Scenario: Module enabled
+- **WHEN** `custom.gif-recorder.enable` is true
+- **THEN** the user environment contains the recorder command and its Wayland recording, selection, encoding, and clipboard dependencies
+
+#### Scenario: Module disabled
+- **WHEN** `custom.gif-recorder.enable` is false
