Variable: ACCESS\_TOKEN\_HEADER

const ACCESS_TOKEN_HEADER: "x-forwarded-access-token" = "x-forwarded-access-token"

Header the Databricks Apps front door forwards the caller’s OAuth (OBO) token on - the default source for every helper here.

Exported because it is a wire contract several packages branch on, not just a default argument: @dbx-tools/appkit’s identity module decides whether a request can use OBO auth at all by its presence, and @dbx-tools/tunnel must know the name to strip inbound copies of it. One spelling, one place.
