/**
 * JinjaAdapter — Conformance Tests
 *
 * Runs the shared adapter conformance corpus (JSX fixtures, template
 * primitives, marker conformance) against the Jinja2 adapter, rendering
 * each fixture end-to-end through real Jinja2 + the bundled
 * `barefootjs.backend_jinja.JinjaBackend` via `renderJinjaComponent`.
 *
 * The Jinja adapter was ported from the Text::Xslate (Kolon) adapter, so
 * the skip / diagnostic sets below start from xslate's and diverge only
 * where the engine genuinely differs. Every divergence carries a one-line
 * rationale.
