Floating links are underlined only on hover

Links within sentences (or otherwise surrounded by non-linked words) are underlined, so they can be seen more easily.

Text link with document icon

A dotted underline (and trailing book icon) indicates a technical term which is defined in the glossary.

If punctuation immediately follows a glossary term, like this, the .term-end style should also be included. This shifts the punctuation closer to the icon.
