Spike: reduce Giraffe's build size

### Background
Our bundle size is fairly large and unoptimized. We should optimize it

### Acceptance Criteria
- The production bundle size has been reduced
- If it's not possible to reduce the production bundle size in a reasonable amount of time, an explanation of the reason it's not feasible and some potential solutions to look at in the future

The issue names no files, tests, or entry points. Start by identifying how the production bundle is measured and built, then investigate the sources of its size. Done means the production bundle is smaller, or the issue documents why reduction is not feasible and records potential future solutions.
