####### JSONSchema-to-form-to-custom-properties generator
#
# The code below was written based on LLM-generated boilerplate.
# I've had to rewrite every function, so at best it was a very convoluted
# way to lookup all necessary function-names.
#
# model: Gemini3 (fast)
# prompt: write a jsonschemaform-tab-to-custom properties-tab blender script.
# The form should appear in a tab of Object properties, and render a
# statically defined jsonschema with: oneOf, anyOf, allOf, $ref & $defs,
# datatypes like float,string,int,boolean, nesting, enums, default, title
# (for human form-display), enumHuman (for human enum display), description,
# pattern, minimum, maximum,
# Regarding output: when clicking an apply-button, write the JSON-object to
# the custom property-tab as 'JSON' with valuetype 'string'.
# If 'flatten' is set on the schema-root, collect all selected key/value
# properties from the form, and write each key/value separately to the custom
# property tab (only integer, string, boolean, float properties).
