# Audience And Word Range Design

**Context**

The app already exposes shared generation controls for script type, themes, and narrative methods. Both conversion mode and creation mode use those controls and persist them locally.

**Decision**

Add two more shared controls in both modes:

- `受众倾向`: `男频` and `女频`, default `男频`
- `字数范围`: `200 - 500`, `500 - 1000`, `1000 - 2000`, `2000 - 3000`, `3000以上`, `不限`, default `不限`

These controls should:

- appear in both modes alongside the existing generation parameters
- use the same pill-button interaction style as the existing filters
- persist via `localStorage`
- be included in all AI generation requests for conversion, single-page creation, and batch creation

**Implementation Notes**

- Keep the values in Chinese only.
- Follow the current state structure in `src/App.tsx` instead of doing a broader settings refactor.
- Extend the AI settings payload passed into `src/services/ai.ts` so prompts can explicitly mention the new choices.
