# Mini Program Script Home Cosmic Background Design

## Goal

Polish the mini-program script generation home page so the headline is centered with comfortable spacing, and the page background gains subtle cosmic motion that matches the current purple/gold style.

## Approved Approach

Use option A: a restrained cosmic background.

## Behavior

- Center the headline `今天有什么心愿想实现`.
- Keep the headline on one line.
- Add a slightly larger gap between the headline and the inspiration section.
- Add background-only cosmic elements:
  - a distant planet near the upper-right edge,
  - a faint smaller planet near the lower-left edge,
  - a few animated meteors moving diagonally,
  - subtle star speckles.
- Background elements must stay behind page content and must not affect tapping inputs, inspiration cards, buttons, or the microphone.

## Implementation Notes

Only `mini-program/src/pages/main/ScriptView.vue` needs to change.

Add a `cosmic-background` layer as the first child of `.script-view`. Set it to `position: absolute`, `inset: 0`, `pointer-events: none`, and a lower `z-index`.

Set `.script-view` to `position: relative` and `overflow: hidden`. Set `.wish-home`, `.generation-view`, and `.result-view` to `position: relative; z-index: 1;`.

Use CSS-only animation for meteors and slow planet drift. Keep opacity low so content remains readable.

## Validation

Run:

```bash
cd mini-program
npm run build:mp-weixin
```

Expected result: build succeeds with no new errors.
