Seattle cost estimate

Calculate a Seattle-area cost estimate. Returns a planning range, point cost, material/labor split, days, and itemized line items.

Material IDs: get_material_options returns exact IDs; a close match (lvp, composite, cedar) also resolves, and an ambiguous one returns the valid list.

Required fields by projectType — ? = optional, (mat) = material ID:
