Include or exclude certain variables when outputting to specific formats

[zackbatist]

Description

I want to control how certain variables get passed to certain output formats. For instance, I want to be able to include the author and date in the PDF output while suppressing this information in the HTML output. Is this feasible?

You only have to write it so:

---
format:
  html:
    title: "HTML Quarto Playground"
  typst:
    title: "Typst Quarto Playground"
---

This is a playground for Quarto.

{{< lipsum 1 >}}

![An image]({{< placeholder 600 400 >}}){#fig-placeholder}

Note that "suppressing" in HTML can also be achieved using (S)CSS: display: none;.
