		 * 2. Working WPCOM/Jetpack connection and fully onboarded Stripe account -> redirect to OVERVIEW PAGE
		 * 3. Specific `from` places -> redirect to CONNECT PAGE regardless of the account status
		 * 4. NO [working] WPCOM/Jetpack connection:
		 *    Initialize the WPCOM registration and:
		 *      4.1 On SUCCESS -> redirect to WPCOM/Jetpack connection screen (Calypso).
		 *      4.2 On ERROR -> redirect to CONNECT PAGE with ERROR message
		 * 5. Working WPCOM/Jetpack connection and:
		 *    5.1 If NO Stripe account connected:
		 *         5.1.1 If we are setting up a test drive account and the auto-start onboarding is enabled,
		 *               we redirect to the CONNECT PAGE to let the JS logic orchestrate the Stripe account creation.
		 *         5.1.2 If we come from the ONBOARDING WIZARD:
		 *                Initialize the Stripe account and:
		 *                5.1.1.1 On SUCCESS -> redirect to STRIPE KYC
		 *                5.1.1.2 On existing account -> redirect to OVERVIEW PAGE
		 *                5.1.1.3 On ERROR -> redirect to CONNECT PAGE with ERROR message
		 *         5.1.3 All other cases -> redirect to ONBOARDING WIZARD
