/**
* Streams a File's bytes straight to the browser — inline by default (a
* browser-previewable type like an image opens/displays directly), or as
* a forced download with ?download=1 (e.g. an explicit "Download" button
* distinct from a thumbnail/preview link pointing at the same file). Only
* reachable via a short-lived signed URL — same auth model as
* Modules\Core\Shipping\Http\Controllers\DownloadShipmentLabelController
* (a valid signature IS the auth check, no separate staff/customer
* session check here) — so any caller that can mint a signed URL to this
* route (the storefront's own custom-field upload flow, or the admin
* order-line display) can hand a viewer a working link without this
* controller knowing anything about who they are or why they're allowed
* to see this particular file.
*
* Looks the File up manually from a plain {file} id rather than relying
* on implicit route-model-binding — registered via loadRoutesFrom() with
* no middleware group (see Providers\FileServiceProvider::boot()), so
* SubstituteBindings never runs and a type-hinted File parameter would
* silently resolve to an empty, non-existent model instead of 404ing.
