Transcription resource - Letter forms - make an edition page?

[ps2270]

Possible to make an Edition page of Letter forms in Ms. Fr. 640:
https://docs.google.com/document/d/1nghSQw5CzTP-UFiO97dCY9LUsaELazVD3Rrre3ERerQ/edit

the Principles of transcription could link out to it.

@tcatapano - we should look into making a .md version of the current googledoc, BnF Letterforms. It may be tricky because of all the small, cropped images and the way they are aligned.

Perhaps a good project for @Pantagrueliste to create a clearer, cleaner version of this in .md? I think even the addition of a table with one column of the typed letter(s) and another for all variations in the manuscript would help things

Decided for MVP: point to the M&K website. Then try to create a durable resource for later releases.
