/**
 * Style resolution for the `wrapBlockNodeView` nodeview decorations.
 *
 * Every exported resolver is a single gate: the `colorSchemeRegistry` + `factory.ts`
 * implementation when `platform_editor_show_diff_color_scheme_refactor` is on, and the verbatim
 * pre-refactor per-scheme constants from `./wrapBlockNodeViewStyles.legacy` when it is off. The two
 * paths are built to emit identical style strings for both shipped schemes, so this is a kill
 * switch for a refactor rather than a behaviour experiment.
 *
 * On cleanup (EDITOR-8281): drop the `isExperimentEnabled` dispatch and the `*Legacy` imports,
 * keeping the `*Next` bodies.
