Sorry for yet another thread about fonts and alignment and whatnot. But in searching for the answers to my questions I've gotten myself a bit confused and turned around, seen some info that looks slightly conflicting with no follow-up, that sort of thing... there's a lot of talk about how these things affect justified text, since that's their main purpose, but I haven't found a clear answer about non-justified text. (My natural assumption would be that there aren't major word-spacing issues to begin with in left-aligned text, but I've seen some hints that there might be, especially when kerning/ligatures come into play?)

This is something that I could test myself, but it would require installing patches and custom dictionaries, and I'd rather not do that unless I know I need them! Currently I don't have any patches/etc. installed. So I'm just hoping that someone either already knows the answers, or someone with these things already installed could do me a big favor and test them real quickly.

With that preamble out of the way, my questions are: in kepubs, do word spacing patches or hyphenation dictionaries have any visible effect on left-aligned (aka ragged right) text, with ligatures/kerning not enabled? Does this change when they are enabled, and is there a difference between webkitTextRendering=optimizeLegibility and webkitTextRendering=geometricPrecision?

I am aware that fonts might complicate this... if anyone happens to have ChareInk and/or Literata Book installed I'd love to know the answers with these two specifically. But really any serif is fine; I'm just trying to get a general sense about whether I should try installing some of this stuff for a better reading experience, or if they don't have much of an effect in my preferred reading alignment.

(Not sure it's relevant, but I have a Libra H2O.)
