We only need to show the totals in the tooltip. Tooltips accpet a component for the tooltip label. The component isn't rendered until the tooltip is triggered.

Move the board total fetching into a tooltip component for the boards. Now we only fire these requests when the user mouses over the board

+Within invocations, the following methods are available from the

+### context.download_and_cache_model(source) -> Path
+
+This method accepts a `source` of a remote model, downloads and caches

+be a direct download URL or a HuggingFace repo_id.
+
+In the case of HuggingFace repo_id, the following variants are

+* stabilityai/stable-diffusion-v4:onnx:vae  -- the onnx variant vae subfolder

+directory using this syntax:
+
+* stabilityai/stable-diffusion-v4::/checkpoints/sd4.safetensors
+
+### context.load_local_model(model_path, [loader]) -> LoadedModel
+
+This method loads a local model from the indicated path, returning a
+`LoadedModel`. The optional loader is a Callable that accepts a Path
+to the object, and returns a `AnyModel` object. If no loader is
+provided, then the method will use `torch.load()` for a .ckpt or .bin
+checkpoint file, `safetensors.torch.load_file()` for a safetensors
+checkpoint file, or `cls.from_pretrained()` for a directory that looks
+like a diffusers directory.
+
+### context.load_remote_model(source, [loader]) -> LoadedModel

+This method accepts a `source` of a remote model, downloads and caches
+it locally, loads it, and returns a `LoadedModel`. The source can be a

+`controlnet_aux` is a dependency of Invoke and appears to have been packaged or distributed strangely. Sometimes, it doesn't install correctly. This is outside our control.
+
+If you encounter this error, the solution is to remove the package from the `pip` cache and re-run the Invoke installer so a fresh, working version of `controlnet_aux` can be downloaded and installed:
+
+- Run the Invoke launcher
+- Choose the developer console option
+- Run this command: `pip cache remove controlnet_aux`
+- Close the terminal window

+    Context manager object that mediates transfer from RAM<->VRAM.
+
+    This is a context manager object that has two distinct APIs:
+
+    1. Older API (deprecated):
+    Use the LoadedModel object directly as a context manager.
+    It will move the model into VRAM (on CUDA devices), and
+    return the model in a form suitable for passing to torch.
+    Example:
+    ```
+    loaded_model_= loader.get_model_by_key('f13dd932', SubModelType('vae'))
+    with loaded_model as vae:
+      image = vae.decode(latents)[0]
+    ```
+
+    2. Newer API (recommended):
+    Call the LoadedModel's `model_on_device()` method in a
+    context. It returns a tuple consisting of a copy of
+    the model's state dict in CPU RAM followed by a copy
+    of the model in VRAM. The state dict is provided to allow
+    LoRAs and other model patchers to return the model to
+    its unpatched state without expensive copy and restore
+    operations.
+
+    Example:
+    ```
+    loaded_model_= loader.get_model_by_key('f13dd932', SubModelType('vae'))
+    with loaded_model.model_on_device() as (state_dict, vae):
+        image = vae.decode(latents)[0]
+    ```
+
+    The state_dict should be treated as a read-only object and
+    never modified. Also be aware that some loadable models do
+    not have a state_dict, in which case this value will be None.
