Remote fonts not recognised when using a brand extension #13685
Description
I have:
- searched the issue tracker for similar issues
- installed the latest version of Quarto CLI
- formatted my issue following the Bug Reports guide
Bug description
Quarto erroneously treats a font URL as a file path, resulting in ERROR: NotFound: No such file or directory, when using a brand extension. Somewhat related to #12267.
Steps to reproduce
Consider this folder structure:
project/
├── _extensions/
│ └── brand-yml/
│ ├── _extension.yml
│ └── brand.yml
├── _quarto.yml
└── example.qmd
example.qmd

A remote location should be supported as described in brand-yml docs. Admittedly, if I move the brand file to the root of the project as _brand.yml, it correctly generates the output (with the font applied) as expected:
project/
├── _brand.yml
├── _quarto.yml
└── example.qmd
It seems like the issue only arrises when using an extension.
