What is the difference between quantum-resistant and quantum-safe?

As a cryptocurrency and finance practitioner, I often come across the terms "quantum-resistant" and "quantum-safe" in discussions about the future of blockchain security. Could you please clarify the difference between these two concepts? Are they interchangeable, or do they represent distinct aspects of security in the context of emerging quantum computing threats? Understanding this distinction is crucial for assessing the long-term security of various cryptocurrency protocols and systems.
