Does anyone have a CSS snippet to remove this "metadata" bar?

This should do it and leave the tag line:

.markdown-preview-view .frontmatter-container-header {
  display: none;
}

Have a look here: Getting comfortable with Obsidian CSS CSS can be overwhelming at times, but you’ll learn a lot poking around with the selector.
