Oh jeez, I didn't realize how much got rolled back.
I asked Melissa about the tiny arrowhead on the Enter prototype, and she responded by telling me she's having the legend guys recut it. This to me means that the small arrow was a screw-up and not a result of something being wrong with the SVG or the instructions I gave her. Hopefully I should have the new key in hand by the end of this coming week.
I expect the actual "Enter" text to be unchanged on the new prototype, so I'm adjusting the other SVGs based on the comparison of the prototype to a real Cherry Enter key. Specifically, the text should be slightly taller. I'll also ask Melissa if making the text bigger allows us to use a thicker cutter, which would match the Cherry keys a bit better.
tldr: We are waiting on a third(!) Enter prototype. This sucks and delays the order, but I think it's worth it to increase confidence in the look of the final keys.
