Implement Mullvad Leta backend support and update README

This commit introduces support for the Mullvad Leta search backend, which is now enabled by default. It includes a new conversion function to transform Leta's search results into a format compatible with Whoogle. The README has been updated to reflect this change, detailing the limitations of the Leta backend and how to switch back to Google if needed. Additionally, the configuration model has been updated to include a setting for enabling/disabling the Leta backend.

+# Mullvad Leta Backend Integration
+
+## Overview
+
+Whoogle Search now supports using Mullvad Leta (https://leta.mullvad.net) as an alternative search backend. This provides an additional privacy-focused search option that routes queries through Mullvad's infrastructure.
+
+## Features
+
+- **Backend Selection**: Users can choose between Google (default) and Mullvad Leta as the search backend
+- **Privacy-Focused**: Leta is designed for privacy and doesn't track searches
+- **Seamless Integration**: Results from Leta are automatically converted to Whoogle's display format
+- **Automatic Tab Filtering**: Image, video, news, and map tabs are automatically hidden when using Leta (as these are not supported)
+
+## Limitations
+
+When using the Mullvad Leta backend, the following search types are **NOT supported**:
+- Image search (`tbm=isch`)
+- Video search (`tbm=vid`)
+- News search (`tbm=nws`)
+- Map search
+
+Attempting to use these search types with Leta enabled will show an error message and redirect to the home page.
+
+## Configuration
+
+### Via Web Interface
+
+1. Click the "Config" button on the Whoogle home page
+2. Scroll down to find the "Use Mullvad Leta Backend" checkbox
+3. **Leta is enabled by default** - uncheck the box to use Google instead
+4. Click "Apply" to save your settings
+
+### Via Environment Variable
+
+Leta is **enabled by default**. To disable it and use Google instead:
+```bash
+WHOOGLE_CONFIG_USE_LETA=0
+```
+
+To explicitly enable it (though it's already default):
+```bash
+WHOOGLE_CONFIG_USE_LETA=1
+```
+
+## Implementation Details
+
+### Files Modified
+
+1. **app/models/config.py**
+   - Added `use_leta` configuration option
+   - Added to `safe_keys` list for URL parameter passing
+
+2. **app/request.py**
+   - Modified `Request.__init__()` to use Leta URL when configured
+   - Added `gen_query_leta()` function to format queries for Leta's API
+   - Leta uses different query parameters than Google:
+     - `engine=google` (or `brave`)
+     - `country=XX` (lowercase country code)
+     - `language=XX` (language code without `lang_` prefix)
+     - `lastUpdated=d|w|m|y` (time period filter)
+     - `page=N` (pagination, 1-indexed)
+
+3. **app/filter.py**
+   - Added `convert_leta_to_whoogle()` method to parse Leta's HTML structure
+   - Modified `clean()` method to detect and convert Leta results
+   - Leta results use `<article>` tags with specific classes that are converted to Whoogle's format
+
+4. **app/routes.py**
+   - Added validation to prevent unsupported search types when using Leta
+   - Shows user-friendly error message when attempting image/video/news/map searches with Leta
+
+5. **app/utils/results.py**
+   - Modified `get_tabs_content()` to accept `use_leta` parameter
+   - Filters out non-web search tabs when Leta is enabled
+
+6. **app/templates/index.html**
+   - Added checkbox in settings panel for enabling/disabling Leta backend
+   - Includes helpful tooltip explaining Leta's limitations
+
+## Technical Details
+
+### Query Parameter Mapping
+
+| Google Parameter | Leta Parameter | Notes |
+|-----------------|----------------|-------|
+| `q=<query>` | `q=<query>` | Same format |
+| `gl=<country>` | `country=<code>` | Lowercase country code |
+| `lr=<lang>` | `language=<code>` | Without `lang_` prefix |
+| `tbs=qdr:d` | `lastUpdated=d` | Time filters mapped |
+| `start=10` | `page=2` | Converted to 1-indexed pages |
+| `tbm=isch/vid/nws` | N/A | Not supported |
+
+### Leta HTML Structure
+
+Leta returns results in this structure:
+```html
+<article class="svelte-fmlk7p">
+  <a href="<result-url>">
+    <h3>Result Title</h3>
+  </a>
+  <cite>display-url.com</cite>
+  <p class="result__body">Result snippet/description</p>
+</article>
+```
+
+This is converted to Whoogle's expected format for consistent display.
+
+## Testing
+
+To test the Leta integration:
+
+1. Enable Leta in settings
+2. Perform a regular web search - should see results from Leta
+3. Try to access an image/video/news tab - should see error message
+4. Check pagination works correctly
+5. Verify country and language filters work
+6. Test time period filters (past day/week/month/year)
+
+## Environment Variables
+
+- `WHOOGLE_CONFIG_USE_LETA`: Set to `0` to disable Leta and use Google instead (default: `1` - Leta enabled)
+
+## Future Enhancements
+
+Potential improvements for future versions:
+- Add Brave as an alternative engine option (Leta supports both Google and Brave)
+- Implement image search support if Leta adds this capability
+- Add per-query backend selection (bang-style syntax)
+- Cache Leta results for improved performance
+
+## Notes
+
+- Leta's search results are cached on their end, so you may see "cached X days ago" messages
+- Leta requires no API key or authentication
+- Leta respects Tor configuration if enabled in Whoogle
+- User agent settings apply to Leta requests as well

 ## FAQ
+
+**What is Mullvad Leta and why is it the default?**
+
+Mullvad Leta is a privacy-focused search service provided by [Mullvad VPN](https://mullvad.net/en/leta). As of January 2025, Google disabled JavaScript-free search results, which breaks Whoogle's core functionality. Leta provides an excellent alternative that:
+
+- Doesn't require JavaScript
+- Provides privacy-focused search results through Mullvad's infrastructure
+- Uses Google's search index (so results are similar to what you'd expect)
+- Doesn't track or log your searches
+
+**Limitations:** Leta only supports regular web search - no images, videos, news, or maps. If you need these features and Google's JavaScript-free search becomes available again, you can disable Leta in settings or set `WHOOGLE_CONFIG_USE_LETA=0`.
+
+For more details, see [LETA_INTEGRATION.md](LETA_INTEGRATION.md).
+
 **What's the difference between this and [Searx](https://github.com/asciimoo/searx)?**
 
 Whoogle is intended to only ever be deployed to private instances by individuals of any background, with as little effort as possible. Prior knowledge of/experience with the command line or deploying applications is not necessary to deploy Whoogle, which isn't the case with Searx. As a result, Whoogle is missing some features of Searx in order to be as easy to deploy as possible.
