/**
 * Staging canvas E2E — opens each of the 13 workspace-panel tabs against a
 * fresh staging org provisioned in the global setup. Asserts each tab
 * renders without throwing and captures a screenshot for visual review.
 *
 * Auth model: the tenant platform's AdminAuth middleware accepts a bearer
 * token OR a WorkOS session cookie. Playwright can't mint a WorkOS
 * session, so we feed the per-tenant admin token (fetched in global
 * setup via GET /cp/admin/orgs/:slug/admin-token) as an Authorization:
 * Bearer header via context.setExtraHTTPHeaders(). Every browser
 * request inherits the header.
 *
 * Known SaaS gaps — documented in #1369 and allowed to render errored
 * content without failing the test (the gate is "no hard crash, no
 * 'Failed to load' toast"):
 *   - Files tab: empty (platform can't docker exec into a remote EC2)
 *   - Terminal tab: WS connect fails
 *   - Peers tab: 401 without workspace-scoped token

    // (e.g. /workspaces/:id/peers, /plugins) yanked the user (and the
    // test) to AuthKit. That's now fixed at the source: api.ts probes
    // /cp/auth/me before redirecting, so a 401 from a non-auth path
    // with a live session throws a regular error instead.

    //      diagnostics, captured by the filter in the assertion
    //      block but having no 401s reach the network is cleaner).

    //      their api calls — an unhandled rejection would surface
    //      as console.error → fail the assertion. Panels SHOULD
    //      handle errors, but until they're all audited, this is
    //      the test's belt to api.ts's braces.
