Related to shakacode/react_on_rails#2914 and follow-up to shakacode/react_on_rails#2909.

Is your feature request related to a problem? Please describe.
The docs IA cleanup in react_on_rails deliberately avoided route changes. The follow-up slug cleanup issue in react_on_rails now needs matching redirect coverage in reactonrails.com so canonical route cleanup does not break existing inbound links.

Describe the solution you'd like
Add a sibling issue in this repo to:

• confirm the current redirect mechanism for docs routes
• add explicit redirects for any doc slug changes approved in shakacode/react_on_rails#2914
• verify deployment order so redirects land before or with the upstream route changes
• keep old docs URLs working during the rollout

Describe alternatives you've considered
The fallback is to keep the current verbose routes and skip slug cleanup entirely. That remains acceptable if redirect complexity outweighs the user benefit.

Additional context
This should stay narrowly focused on redirect behavior and rollout safety. If the exact redirect map is not known yet, this issue can remain blocked on the final route table from shakacode/react_on_rails#2914.
