Also included in the Nucleus.
We can divide the board into as many 'zones' as we see best for different types of learning scenarios. No division is the most common experience. The board as one thing is the goal.
Yet, putting boundaries up, then erasing them is a powerful way to learn.
We use this division for many things, including Linear Versions.
For reading, we move the boundaries...
Decide for yourself how you think of the fretboard. These zones are for learning processes and are meant to be transcended once we have a global view of our board.
