# Theme-Park Theme CSS Synchronization Script
#
# This script synchronizes the CSS files needed for the theme-park.dev Unraid theme
# into the Dynamix CSS styles folder. The script creates destination subfolders if
# they don't exist and performs rsync for each subfolder. It then updates the @import references 
# in the CSS files so the files get correctly loaded by the client.
#
# This script is intended for users of the "Theme Engine" plugin, allowing custom
# styling to be added into the HTML head that references the copied CSS files.
#
# After running this script, you can use the following code snippet as an example
# in your HTML head (Custom styling (advanced)) to include the copied CSS files using the "Theme Engine" plugin:
#
# <!-- Example for Theme Engine plugin -->
# </style>
#   <link type="text/css" rel="stylesheet" href="/webGui/styles/theme-park/css/base/unraid/nord.css"/>
#
# Tip: You can use the "User Scripts" plugin in Unraid to schedule this script to run
# automatically when the Unraid array starts.
