Review paradigm styling

[eddieantonio]

I think it's time to reconsider how the paradigms are presented. This includes the presentation of:

• pane headers
• row labels
• column labels
• observed wordforms
• unobserved wordforms
• inflections with multiple possible realizations (see feat: compound rows in paradigms #858)

I gather most of this will be CSS tweaks, however, I think there might be some HTML tweaks as well. If we decide to use slashes to separate multiple possible realizations, I think a whole lot of Python code would need to be deleted too 😈

Concerning how to distinguish linguistic content (the cells that the FST generates) from the row and column labels, #568 has a relevant observation/suggestion, based on old NDS, as illustrated in the image below:

I suppose the blue color was motivated by the labels in question having pop-ups with alternative relabelings.

Beyond the above, there are some elements in #505, namely:

• showing optionally morpheme boundaries (option b.)
• showing the English phrase translations as pop-ups to the Cree wordforms in the individual cells.

We might consider the rest, i.e. presenting in a pop-up the full range of additional information for each cell with Cree word-forms, separate of this issue.
