...and it's already implemented! I thought this day would never come.
And the down arrow is using the same SVG with a `transform: rotate(180deg)` too!
Truly incredible developments.
This is some excellent planning. When a future request comes in for east votes and west votes, they can just update the rotate() parameter and push the changes straight to prod.
If it's just a background-image, why not just build the triangle in CSS? Saves a network request (and a whopping 525 bytes)
