# Generates properly formatted input JSON for search_media_cms_channels MCP tool.
# Cross-platform compatible: Mac, Windows (Git Bash/MSYS/Cygwin), Linux, POSIX
#
# Usage:
#   bash build_cms_search_input.sh --keywords "car,automobile,vehicle" --taxonomies "Modern,Luxury" --locale "en_US"
#   bash build_cms_search_input.sh --keywords "car" --taxonomies "Luxury"
#
# Examples:
#   # With empty keywords
#   bash build_cms_search_input.sh --keywords "" --taxonomies "Bright,Spacious" --locale "en_US"
#
#   # With empty taxonomies
#   bash build_cms_search_input.sh --keywords "logo,brand" --taxonomies "" --locale "en_US"
#
#   # With page parameters
#   bash build_cms_search_input.sh --keywords "car" --taxonomies "Luxury" --locale "en_US" --limit 10 --offset 0
