01 — The energy map
===================

Score every section 1–10 before you edit: 3, 5, 8, 5, 8, 2, 10.
Never let two neighbouring sections share an energy number.
The LAST chorus is the loudest moment — save one trick for it.
The breakdown drops below the intro. The fall makes the final chorus.
Choruses are made by verses: if the chorus feels small, thin the section before it.
