I created a custom object called Usage that has a lookup relationship to the standard Account object. I am trying to create a Visualforce page that will display all of the fields from a Usage record directly on the Account page if the two are linked via the lookup field.

I am new to VF, and I created a VF page with the following code:

<apex:page standardController="Account">

<apex:pageBlock title="Usage">
    <apex:pageBlockSection>
        <apex:outputField value="{! Account.Usage__c.Name }"/>
        <apex:outputField value="{! Account.Usage__c.Last_User_Login_Date__c }"/>
        <apex:outputField value="{! Account.Usage__c.Request_Manager_Enabled__c }"/>
        <apex:outputField value="{! Account.Usage__c.Users__c }"/>
    </apex:pageBlockSection>
</apex:pageBlock>
    
</apex:page>

However, I get the following error when trying to save: Could not resolve the entity from value binding '{Account.Usage__c.Name}' can only be used with SObjects, or objects that are Visualforce field component resolvable.

I looked into SObjects but am unclear what the issue is.
 

I'm doing the simple lightning components challenge and have hit this problem in my existing trailhead org and a brand new dev org that I've just created:
