# Publish Doxygen HTML to the repository Wiki via Gitea Actions
# Requirements:
# - Create a repository secret named WIKI_TOKEN with a Personal Access Token that has write access.
# - Ensure the Wiki is enabled for this repository.
# - Doxygen output is expected at docs/html (from Doxyfile: OUTPUT_DIRECTORY = docs).
