Overview

Lookup bounds and values are decimal(20, 6), and a float round-trip loses precision above 15 significant digits — on numbers that are tax brackets. So they leave as JSON strings, which CastDecimal parses back without ceremony.

to_s("F") rather than plain to_s, which renders 0.1 as "0.1e0". The core gem makes the same choice writing decimals into source_config (CastJsonSafe), so an exported file and an imported one agree on what a decimal looks like.
