## Using Custom Color Palettes
To create custom color schemes:
1. **Copy template files** from `./templates/` directory:
- `light.custom.css``media/templates/site/mokocassiopeia/css/theme/light.custom.css`
- `dark.custom.css``media/templates/site/mokocassiopeia/css/theme/dark.custom.css`
2. **Edit the variables** in the copied files to match your brand
3. **Enable in Joomla**:
- Navigate to: System → Site Templates → MokoCassiopeia
- Under "Theme" tab, set palette to "Custom"
- Save changes
4. **Note**: Custom files are gitignored and won't be committed to the repository
5. **On upgrade**: When the template is updated, `script.php` automatically runs `sync_custom_vars.php` to detect any new variables added to the starter templates and inject them into your existing custom palette files. Your existing values are never overwritten — only genuinely new variables are added. You can also run this manually:
```bash
php templates/mokocassiopeia/sync_custom_vars.php --dry-run # preview what would be added
php templates/mokocassiopeia/sync_custom_vars.php # apply missing variables
```
