- Pack 8 leaves into 1 peat node.
- Leave peat nodes near soil and moisture to decompose further
into humus.
- Humus is a high-quality soil that works like dirt in most
ways, but grows trees quite a bit faster.
- Humus converts to dirt via grass (and eventually maybe other
plant cultivation activities).
Much TODO:
- Primitive adze should not harvest trees whole; need to split into
planks from end only.
- Not entirely satisfied with crafting experience from gameplay nor
API perspective.
- Need an easier way to register these kinds of recipe checks.
- Need more gameplay actions to commmit a craft, e.g. have to pound
the tool head into place.
