Reader mode paddings should be minimal for width < 1280px (Android)

There is no sense in keeping such big borders in Reader View mode while you have a small display.

Tested on

- Huawei MatePad 11.5 S PaperMatte - both modes spend half of the space just for useless borders.

- Samsung Note10+ - horizontal orientation is terrible.
