Depends on parlez-vous/server#110

An update on this:
Right now list of comments are shown unstyled, we will need a card component, i'm looking at how tailwind utility classes work which are used in the project for styling.
Elm now has native tailwind support via https://package.elm-lang.org/packages/matheus23/elm-default-tailwind-modules/2.0.1/, so instead of using postcss we can directly use it too.

Another update:

This required a bunch of changes to show the comment date in the user's local timezone, specifically the app model structure was changed so that user's time zone information could be retrieved at app init.

Here are some screenshots, the post name is still unimplemented since that requires back end support
