# UI content is loaded via the \`sandbox_domain\`.
# "Content Security Policy" headers prevent content loaded via the sandbox
# from accessing privileged information.
# These variables must be different to take advantage of CryptPad's sandboxing techniques.

# -
# - The server is configured to load files from the '/customize/' path
# - preferentially from 'cryptpad/customize/', and to fall back to
# - 'cryptpad/customize.dist/' if they are not found.
# -
# - If you wish to customize cryptpad, please **copy**
# - '/customize.dist/' to '/customize' and then edit it there, this way you will
# - still be able to pull from (and make pull requests to (!) the git repository.
