Removed every named/linked reference to the three real personal projects
this system was synthesized from (repo names, GitHub links, and specific
enough functional descriptions to identify them), across index.md,
README.md, rationale.md, both foundation pages, and both pattern pages.
The design rationale itself is unchanged — which visual property came
from reading real, running apps rather than a spec — just without saying
which apps.

Also renamed the 'Why arbitrary' nav label and page title to 'Rationale':
as a page title it read as an incomplete sentence rather than a question
about the name.
