defmodule PinchflatWeb.ApiAuthPlug do
@moduledoc """
Authenticates API requests using a Bearer token.
The token is read from the `PINCHFLAT_API_TOKEN` environment variable.
If the environment variable is not set, API authentication is disabled
(useful for development and testing). In production, you should always
set this to a secure value.
Clients should send the token in the Authorization header:
Authorization: Bearer <token>
