Code for Example 3 (FORE) currently disabled as it errors within the Quarto page

[hurak]

Code for Example 3 (FORE) currently disabled as it errors within the Quarto page, while running perfectly within vscode. Perhaps some issue with the environment, but I have explored whatever I could think of. I discussed it at quarto-dev/quarto-cli#10837 and while the advice recommended there (--execute-daemon-restart option for quarto) worked for a stripped-off version of the code, I am still failing to resolve the original full problem.
