⚙Tech Debt: Create internal visual test routes

[TGlide]

Currently, our only examples are the ones we show in the docs. Sometimes we want to do a visual test of some edge cases, and currently, the only way to do so is modifying the example file, and then undo the change when it goes live.

Instead, I want to have an easy way to have multiple example files per component, and be able to preview them. On production, these routes will be hidden away.
