= Main Heading

This is the introduction section with some styled text. We have *strong emphasis* and _italic text_ for emphasis.

#important-note[This is an important note that stands out with custom styling using show rules.]

== Subheading

Here's a paragraph with justified text and proper line spacing. The styling rules make the document look more polished and professional.

- Item one
- Item two with a #link("https://typst.app")[link to Typst]
- Item three

== Another Subheading

More content follows here with different styling applied through set and show rules.
