Generate a Photoshop script to: $ARGUMENTS

## Instructions

1. Determine the target API:
   - **UXP** (default, Photoshop 2022+): modern async JavaScript
   - **ExtendScript** (legacy, Photoshop CS6+): JSX/ES3-like syntax
   - Ask if unclear which version the user needs
2. Write the script following Adobe's API conventions
3. Include error handling for common failures (no document open, locked layers, etc.)
4. Add comments explaining each major step

## UXP script structure

```javascript
const { app, constants } = require("photoshop")
const { executeAsModal } = require("photoshop").core

async function main() {
    const doc = app.activeDocument
    if (!doc) {
        console.error("No document open")
        return
    }

    await executeAsModal(async () => {
        // Your operations here
        const layer = doc.activeLayers[0]
        layer.opacity = 50
    }, { commandName: "Script Name" })
}

main()
```

## ExtendScript structure

```javascript
#target photoshop

if (app.documents.length === 0) {
    alert("No document open")
} else {
    var doc = app.activeDocument;
    // Your operations here
    var layer = doc.activeLayer;
    layer.opacity = 50;
}
```

## Common operations reference

| Operation | UXP | ExtendScript |
|-----------|-----|-------------|
| Get active doc | `app.activeDocument` | `app.activeDocument` |
| Create layer | `doc.createLayer()` | `doc.artLayers.add()` |
| Set blend mode | `layer.blendMode = constants.BlendMode.MULTIPLY` | `layer.blendMode = BlendMode.MULTIPLY` |
| Apply Gaussian blur | `await batchPlay([{_obj:"gaussianBlur", radius: 5}])` | `layer.applyGaussianBlur(5)` |
| Save as PNG | `doc.saveAs.png(filePath, options)` | `doc.saveAs(file, pngOpts, true)` |

## Constraints

- Always wrap UXP operations in `executeAsModal`
- ExtendScript uses `#target photoshop` directive at the top
- Test with a duplicate document first — scripts can't easily undo
