What it models, and when not to use it

No hand-written part: this entry’s source has not been written (the docs walk counts it).

Settings

Setting	Type	Default	Dimension	Role	Default’s kind
k	Annotated[Quantity, Force / Length]	{"unit": "kg s^-2", "value": 1.7}	kg s^-2	none declared	none: required
x0	Annotated[Quantity, Length]	{"unit": "m", "value": [0.05, -0.02, 0.01]}	length (m)	none declared	none: required

Each role and default’s kind is the entry’s setting_roles (mime.registry.SettingRole); a setting that declares none is required.
