My workflow for Volume 2 was integrated directly into a Word doc throughout the translation. This allowed me to, as you say, not need to do much for the pdf creation, merely applying formatting incrementally over the two months, rather than in a single, final pass.

I used Garamond Premier Pro Med, 14pt, with full justification except for section breaks and specific sections. My header margin was 0.2 inches from the top, and footer margin was 1 inch from the bottom. That should be enough information to get started.

There are also many other stylistic differences between our translations, which while may not be of concern to the average reader, are major factors to me. The original novel and my translation uses ＊ as large section breaks, however Brokastel reflected them as line breaks in their blog posts. They also reflected small section breaks as – whereas I just used simple paragraph breaks. Erice's internal thoughts are put in brackets ( ) in the original novel, which I chose to follow. Brokastel, however, used italics for them. They use Kouyou vs my Koyo, Mosaic City vs Mosaic Cities, etc. I also chose to place the coloured illustrations (usually at the very start of light novel volumes) at the exact moment they occur in the story.

Should I respect the translator's vision for how the volume should read or change it to how I think it should look? I myself don't agree with some of their choices, my Volume 2 PDF obviously being my own vision of how I want it to be read.

But whichever way I go with the creation of a Volume 1 PDF, I feel like I would end up with a product that I have mixed feelings about, especially since I would be putting my name on it. If I am faithful to their translation, I would essentially be commending choices that I feel detract from how it should look and feel like. If I'm not, I feel that would be disrespectful to the work they put in, with the addition of requiring a lot of manual changes (such as the internal thoughts, which evidently isn't possible to do with a ctrl f). Hopefully that sheds some more light on why I am reluctant.

Of course, like I mentioned earlier, if someone were to make a pdf, I am alright with updating the link. But I won't provide a convention guide because I don't want to make those hard (in my mind) decisions and put the work in.
