Make it harder to accidentally hit Esc on Lily58

Too often I find myself hitting escape when I meant to type grave for code reference stuff in Markdown-like contexts. Sometimes that can lead to frustrating losses of work. For example, when editing a previous message in Slack, a single tap of Esc instantly discards all changes--definitely not what I want when I meant to begin a code segment in the edited message.

Come up with a way to either guard Esc from accidental presses or to definitively retrain fingers to avoid Esc in those circumstances.

Right now I am thinking a hold-tap on the Esc key that only sends Esc after a fairly significant hold (maybe 500-600ms?), but sends backtick/grave when tapped. Some kind of tap-dance could possibly also work.
