    # Usage:
    # 1. In regular text: ":mycode: Some text" - icon replaces shortcode inline
    # 2. In markdown lists: "- :mycode: List item" - icon replaces bullet with color
    #
    # To add new shortcodes:
    # 1. Add entry to this dict: ":mycode:": "\uf000"
    # 2. Use in template descriptions or markdown content
    # 3. Shortcodes are automatically replaced when markdown is rendered
    # 4. List items starting with shortcodes get colored icons instead of bullets
