+Simple utility to convert a raw text file into a flat JSON card.
+The input format is assumed to be a plain text where each line contains a key and value separated by a colon.
+Example:
+    title: My Card
+    description: This is a test.
+    tags: python, example
+
+The output will be a JSON object with the extracted fields.
