[FEATURE]: Generator needs to not generate images if suitable images already exist #146
Description
Is your feature request related to a problem? Please describe.
The generator will sometimes generate images when it has already generated images before.
If generator knew about existing file assets, it could re-use those.
Describe the solution you'd like
Give generator knowledge about file assets.
📝 User Goal
As a use I expect generator to re-use previously generated images, but sometime when it reworks the spec, it will generate new images because it doesn't know about the ones that already exist.
✅ Acceptance Criteria
- When generator is processing spec, it should know about files that it can access.
