Raw dials

Under the macros are about eighty raw parameters: starcanopy dials lists each with its default and range. They are for scripting, not steering -- the macros are the controls -- and they are the base the macros move from: an override of exposure is what bright doubles.

Set them in the project's [overrides], or on the command line:

./build/starcanopy render night.toml --set galaxy-style=lenticular --set open-clusters=10

A few that are useful on their own:

Dial
seed	which sky; the same seed is always the same sky
nebula	off shows the galaxy and its stars alone
galaxy-style	the galaxy's type -- auto by seed, or barred-spiral, grand-design, flocculent, lenticular
galaxy-radius, galaxy-height	where the observer is, auto by seed
open-clusters	open clusters about a sky, typically; 0 none
accent-near	how strongly the sky's objects are drawn near

A dial that belongs to a macro -- galaxy-place, which galactic moves -- is set through its macro only.
