I once made a Pokédex page for Pokémon Showdown, but I never really got around to promoting it:

It's a similar idea to yours, in terms of making it modern, although I never got around to making it work offline, but it might be interesting to compare how they're similar and how they differ.

Maybe if there's interest, I should put its source up on GitHub and maybe write up some details of how I wrote it.
