Start with the smallest reliable input
Use CSS utilities with a short real sample before pasting a large payload. Smaller inputs make syntax, encoding, and formatting mistakes easier to see.
Keep sensitive data out
Browser-based utilities are useful for speed, but production secrets, private tokens, customer data, and internal hostnames should still be redacted.
Copy only after checking the result
Generated output should be treated as a draft until you confirm the target runtime, syntax variant, or platform behavior.
