Working on more, but nothing exists off-the-shelf for >300ppi eink. No one has ever done eink under magnification like this so higher density screens don't exist (yet). We made a custom bitmap font system and font to squeeze every bit of optimization out of this screen that we can. Text rendering isn't pristine at this low res but it's good enough to not hinder reading. https://x.com/johnboiles/status/1715136868290081104?s=20
