Quarto 1.8.1 and Highlight-text does not work w/o brand.yml #12679
Description
Bug description
A simple test with just "highlight-text" does not render pdf with the color.
Steps to reproduce
---
title: "Test of Highlight-text Quarto Extension"
format:
pdf:
papersize: a4
filters:
- highlight-text
#brand:
# color:
# palette:
# fg: "#b22222"
keep-tex: true
---
## Font Colour
```markdown
[Red text]{colour="#b22222"}
```
[Red text]{colour="#b22222"}Actual behavior
The example above does not render the "Red text" in red in the pdf file. The tex file just contains {Red text}. After commenting out the brand section, the text is rendered correctly in the pdf file.
Expected behavior
The filter should work w/o stating a brand section.
