file description / titles

I believe every file now has a title and + description.

However, the logic isn't consistent.

**Goal**:
```markdown
---
Title: [Page Title]
description: [page description - single sentence]
layout: page
---
content
```

**Reality**:
1. there are pages with 2 titles
```markdown
---
Title: [Page Title]
description: [page description - single sentence]
layout: page
---
# Page Title
```

2. There are pages with 1 word description
3. There are pages with a full paragraph description
4. there are pages where we have `file` or `path` in "header" and pages where we do not.
