Abstract Render Blocks

Abstract Render Blocks (ARB) is a deterministic rendering tool that turns validated YAML data into concrete output files using simple templates.

ARB exists to make output generation predictable and repeatable: same inputs, same outputs. If the input does not match the contract, it should fail loudly.

ARB keeps logic out of templates. Templates should be boring: substitute values, repeat lists, gate optional blocks. If you need complex branching, redesign schema/data so output remains deterministic.

ARB is not a general-purpose template engine. It does not guess, infer, or mutate your data. It does not "helpfully" coerce types. If something is missing or ambiguous, it should fail.
