Is timing belt replacement realistically DIY on a 2015 model with 95k miles?

[JacobW]

My car is a 2015 model with about 95,000 miles, and the maintenance schedule recommends inspecting or replacing the timing belt soon. I'm mechanically inclined enough to do basic work, but this job seems intimidating due to the precision required and the risk of catastrophic engine damage if it's done incorrectly. For those who have tackled this themselves, is a timing belt replacement a realistic DIY project for a careful amateur with the right tools, or is it universally worth paying a professional? What specific special tools, like a crankshaft pulley holder or cam locking kit, are absolutely necessary, and what are the most common mistakes made during the process that I should be hyper-aware of?
