`r basename(pfx)`

Projection: r P$name (r P$res resolution)
Planning unit cost: set to 1
Objective function:
- add_min_set_objective(): Minimize the cost of the solution whilst ensuring that all targets are met
Feature targets:
- r rel_target*100% of each input feature amount
- Physical:
  - phys_vents: hydrothermal vent count
  - phys_seamounts: seamounts count (3 depth classes)
Regionalization:
- none, ie global
