9/// Strongly emphasizes content by increasing the font weight.
10///
11/// Increases the current font weight by a given `delta`.
12///
13/// # Example
14/// ```example
15/// This is *strong.* \
16/// This is #strong[too.] \
17///
18/// #show strong: set text(red)
19/// And this is *evermore.*
20/// ```
21///
22/// # Syntax
23/// This function also has dedicated syntax: To strongly emphasize content,
24/// simply enclose it in stars/asterisks (`*`). Note that this only works at
25/// word boundaries. To strongly emphasize part of a word, you have to use the
26/// function.
