The corners have a radius of 2.4, maybe we can make them sharper to be 2.

[jamiemlaw]

If that were the only change, it would bring the corners too close to the edge of frame.

Trying some slight redraws with the goal to keep the diagonal lines on-grid. These aren't final, but they illustrate a couple of potential issues:

Open lucide studio

The north-each and south-west sticky-out-bits are now aligned to half pixels, making them blurry at low resultions

Bringing them in further and the optical volume is somewhat reduced from what it was previously, and it introduces some 2-pixel-gap violations.
