Maintenance

• The common JoliCode footer is vendored from jolicode/oss-theme and pasted inline in index.html (inside the <div id="snippet-joli-footer"> block), so it renders without any fetch — including when opening the page from the filesystem. To update it, re-run this command from the repository root, re-apply the two substitutions, then replace the <div id="snippet-joli-footer"> block in index.html with the result:

  curl -o joli-footer.html https://raw.githubusercontent.com/jolicode/oss-theme/refs/heads/main/snippet-joli-footer.html
  sed -i 's/#GITHUB_REPO/jolicode\/composer-cheatsheet/g' joli-footer.html
  sed -i 's/<!-- #SUBTITLE -->/Found a typo? Something is wrong in this documentation?
