Resolve relative font paths to absolute paths before passing them to typst compile. This fixes the issue where font-paths specified in extension configurations weren't being found when the input document was in a subdirectory. The extension mechanism resolves font-paths relative to the input document, but typst compile may run from a different working directory. By converting relative paths to absolute paths using the input directory, the fonts are now correctly located. Adds a test case that verifies extension font-paths work correctly when the document is in a subdirectory. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Only resolve font paths that come from extensions (paths containing _extensions or starting with ..) relative to the input directory. Other relative paths like .quarto/typst-font-cache should remain relative to the working directory where typst runs. This fixes the issue where font-paths specified in extension configurations weren't being found when the input document was in a subdirectory, while preserving correct behavior for brand font cache paths. Adds a test case that verifies extension font-paths work correctly when the document is in a subdirectory. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

There was a problem hiding this comment.
Ugh, this is a messy fix - might be better to understand why we are using file-relative paths here and use project-relative instead.

…13917) Extension-resolved logo paths (containing _extensions or starting with ..) are already relative to the input document and should not have the project offset applied. This fixes rendering Typst format extensions with logos when the document is in a project subdirectory. The same pattern was applied to font-paths in #13745 / PR #13902.

Summary
typst compilefont-pathsspecified in extension configurations weren't being found when the input document was in a subdirectoryProblem
When using
font-pathsin a custom Typst format extension, relative paths weren't working because:typst compileruns from a different working directory (project root or temp dir)Solution
In
src/command/render/output-typst.ts, convert relative font paths to absolute paths by joining them withinputDir(the directory containing the input document) before passing totypstCompile.Fixes #13745
Test plan
tests/docs/smoke-all/typst/extension-font-paths/verifies no "unknown font family" warning when using extension with relative font-paths from a subdirectory🤖 Generated with Claude Code
