Remove dead legacy assets and print-only paths

Clean up stale site content that is no longer referenced by active
layouts or pages, so redesign diffs are easier to review and reason
about.

Remove obsolete frontend artifacts that were effectively dead code:
tooltips export files, shuffle/throttle scripts, print layouts, and
their local print CSS/font dependencies.

Simplify active rendering paths by removing unused map include logic
from `page` layout and dropping tooltip collection defaults from
`_config.yml`.

This reduces maintenance surface and prevents unrelated legacy content
from obscuring redesign-focused changes.
