/* RESET */
/* So here's the trick, we must reset to manage a number of problems once and for all:
- HTML5 backwards compatibility (EPUB 3 file in EPUB 2 app);
- user settings (e.g. line-height on Kobo and Kindle);
- CSS bloat (DRY);
- KFX for which a reset using `border: 0` seems to disable support;
- etc.
It all started as a normalize and became a reset given the magnitude of the task.
