Overview

Opt-in renderer that resolves each key through Liquid, enabling dotted access, drops (e.g. company.name }), and filters. Requires the liquid gem. It is loaded here, when a host instantiates this renderer, so apps on the default renderer never pull it in.

Security: only the chip's key is parsed as a Liquid template, never body text, so } or % an author types stays literal. The resolved value is injected as a DOM text node and escaped per output format by the resolver, so drops must NOT pre-escape their values.

assigns is the Hash passed to Liquid: string values and/or Liquid::Drop instances.
