## Global folder title source setting

navigation, docs.yml, frontmatter

Set a default `title-source` for all folder navigations using the new `folder-title-source` option in `settings`. Individual folders can still override this value with their own `title-source`.

**`docs.yml`**

```yaml docs.yml
settings:
  folder-title-source: frontmatter

navigation:
  - folder: ./pages/guides         # uses frontmatter (from global setting)
  - folder: ./pages/reference
    title-source: filename          # overrides global setting
```
