Shopify CLI theme access denied for store owner and Theme Access password both fail on merchant store

In which of these areas are you experiencing a problem?

Expected behavior

Store owner account path
After shopify auth login, running:
shopify theme list
should authenticate successfully and return the store’s themes instead of denying CLI development access.

Theme Access password path
Running:
shopify theme list --password
should authenticate against Theme Access successfully and return the theme list instead of 401 Invalid API key or access token.

Follow-on behavior
Once authenticated by either method, shopify theme push should allow upload of the prepared theme files to the store.

Actual behavior

Store owner account auth appears to succeed, but store-scoped theme commands fail with:
You are not authorized to use the CLI to develop in the provided store: drinkcopal.myshopify.com
Fresh Theme Access passwords also fail for the same store with:
401 Invalid API key or access token (unrecognized login or wrong password)
Because both auth paths fail, CLI theme commands such as shopify theme list and shopify theme push cannot be used against my site.

Reproduction steps

Install or upgrade Shopify CLI to 3.94.3.
Log out of any existing CLI session with:
shopify auth logout
Log back in with the store owner account:
shopify auth login
Run a store-scoped theme command:
shopify theme list --verbose
Observe the error:
You are not authorized to use the CLI to develop in the provided store: drinkcopal.myshopify.com
In the same store, create a fresh Theme Access password using the Theme Access app.
Run the same theme command using the fresh password:
shopify theme list --store drinkcopal.myshopify.com --password --verbose
Observe the error:
401 Invalid API key or access token (unrecognized login or wrong password)

Verbose output

Owner-account auth path:
- `shopify auth login` succeeds
- `shopify theme list --store drinkcopal --verbose` fails during token exchange for `shop.admin.themes`
- Final error: `You are not authorized to use the CLI to develop in the provided store: drinkcopal.myshopify. com`

Theme Access path:
- `shopify theme list --store drinkcopal.myshopify.com --password <fresh-password> --verbose`
- request goes to `https://theme-kit-access.shopifyapps.com/cli/admin/api/unstable/graphql.json`
- final error: `401 Invalid API key or access token (unrecognized login or wrong password)`
