In development, import from @solana/kit as usual and the full message is thrown. In production the message is stripped to keep bundles small; the error object still carries error.context with the same values this page decodes, and isSolanaError(err, SOLANA_ERROR__PROGRAM_CLIENTS__INSUFFICIENT_ACCOUNT_METAS) lets you branch on it.
