During project setup, I misunderstood this suggestion for how to use the console_error_panic_hook crate. I created a "console_error_panic_hook" feature flag, but I never used it to conditionally compile the code that actually sets the panic hook, which is done here in the example I was following. Many thanks to Luke Chu for catching this!

We can set the panic hook by adding the lines

// set the console error panic hook
#[cfg(feature = "console_error_panic_hook")]
console_error_panic_hook::set_once();

at the beginning of main.
