// Regression for #6703: rtkConfigSchema uses Zod .strict() but was missing the
// `enableRenderers` field that DEFAULT_RTK_CONFIG (and the RTK engine's own
// configSchema) already define. The frontend reads DEFAULT_RTK_CONFIG (which
// carries enableRenderers), sends the full object back on save, and .strict()
// rejects the unknown key → HTTP 400 "Unrecognized key: enableRenderers".
// This broke PUT /api/settings/compression, POST /api/context/rtk/test, and
// PUT /api/context/rtk/config.
