## Data Model
Stored in `chrome.storage.local`:
- `folders`: array of folder objects.
- `autoPaste`: boolean toggle for auto-insert behavior.
- `aiOnSelectionEnabled`: enable/disable AI on Selection menu.
- `aiTargets`: list of AI targets (name, base URL, query param, paste fallback).
- `selectionPrompts`: list of selection prompt templates using `{{text}}`.
Example folder item:
```json
{
"id": "uuid",
"name": "General",
"prompts": [
{
"id": "uuid",
"title": "Summarize",
"text": "Summarize the following text...",
"timestamp": "2026-02-16T00:00:00.000Z"
}
]
}
```
Example AI target:
```json
{
"id": "uuid",
"name": "Gemini",
"baseUrl": "https://gemini.google.com/app",
"queryParam": "",
"usePasteFallback": true
}
```
Example selection prompt:
```json
{
"id": "uuid",
"name": "Translate to Russian",
"template": "Переведи на русский, сохраняя стиль и тон:\\n\\n{{text}}",
"timestamp": "2026-02-16T00:00:00.000Z"
}
```
