AFAIU, there are two main aspects that need to be changed for people who
need larger fonts (for blind, fonts are non-issue, I think):
1. Font size
2. Contrast in font colors

AFAIU, font size is mostly a question of changing the default
font. Everything else will inherit the font size.

For contrast, we already have some work in
module-*-deuteranopia/tritanopia themes.

We may need an additional "high-contrast" theme (if modus-themes do not
already provide sufficient contrast), which does not look like something
impossible to do.

Samuel, please correct me if my ideas are wrong.

Here, I'd like input from Samuel and Raman:

   May you share which Emacs options should be adjusted to suite your
   special needs?

With input from Samuel and Raman, we can hopefully discuss the
design. Later, we can make a call on the mailing list and other forums
asking similar users to provide their input, so that we can figure out
which defaults can be changed.
