Pause preview updates when the workspace config is not saveable, surface that state in the Live Preview panel, and treat incomplete threshold color setups as real blocking errors so MangoHud preview never sees the bad intermediate state.
Break the oversized overview page into focused dashboard submodules and
centralize the repeated validation/save-button refresh flows used by page
widgets. This keeps the UI behavior stable while making future edits less
fragile and easier to reason about.
