/* Hanzo Studio deep-link — open a saved workflow (and optionally run it) straight
 * from a URL, so a link in the gallery / console / chat lands you on the graph
 * ready to render.
 *
 * Params (query string or hash, e.g. ?org=karma&workflow=fashion/shoot_valentina.json&run=1):
 *   org        active org to scope userdata + render output to (sets the studio
 *              session org cookie BEFORE loading, so a re-run dispatches to the
 *              org's BYO-GPU and lands the output in that org's gallery).
 *   workflow   path under the user's workflows/ dir (e.g. "fashion/shoot_x.json").
 *   run        "1" to auto-queue the graph once loaded (re-run in one click).
 *
 * Injected as the last <script> by branding/patch_deeplink.py so window.app
 * exists. Guarded end-to-end: a bad param logs and no-ops, never throws.
