a note:

basically we have 3 ways to define a font (collection):

- selectfont: works find when fonts have 'correct' names and come in 
consistent 'sets' (which is not always the case)

- typescripts: for long term stable style usage this is best because one 
uses filenames and can even rename font files then so that updates don't 
clash (typescripts can be in styles or in separate files)

- single font: for specific usage, like special fonts or titling; 
definition by name or file or spec but probably most oiften by file 
(just to be sure); although one can use abstraction by name this methoid 
is not used for collections

mechanisms like fallbacks work for all but may need additional definitions

design siszes can complicate matters but there are no many
