Add Generation Parameter (MooshieUI)

6 touchpoints, in order. New workflow-only params still need Rust + TS types if exposed in UI.

Gather from user

1. Name (TS camelCase, Rust/iface snake_case)
2. Type + default
3. Templates: txt2img | img2img | inpainting | upscale | all
4. ComfyUI node + input field name

1. src/lib/types/index.ts

export interface GenerationParams {
  new_param: SomeType;
}

2–4. src/lib/stores/generation.svelte.ts

newParam = $state<SomeType>(defaultValue);

// loadSettings()
if (saved.newParam !== undefined) this.newParam = saved.newParam;

// saveSettings()
newParam: this.newParam,

// toParams()
new_param: this.newParam,

Use !== undefined for bool/number defaults that can be 0 or false.

5. src-tauri/src/comfyui/types.rs

pub new_param: Type,
// or
pub new_param: Option<Type>,

6. src-tauri/src/templates/{mode}.rs

"node_input": params.new_param,

Verify

cargo check --manifest-path src-tauri/Cargo.toml

- [ ] Interface snake_case field
- [ ] Store $state + load/save + toParams()
- [ ] Rust GenerationParams field
- [ ] ≥1 template references param

If UI needs i18n: add keys to all files in src/lib/locales/ (parity with en.ts).

For new workflow modes, use workflow-template-builder skill after params exist.
