+/**
+ * zitadel-roles.mjs — diagnose and repair the OpenClaw Platform project's
+ * role keys + customer authorizations. Group A of the bug triage.
+ *
+ * Subcommands
+ * -----------
+ *   diagnose             Print the project's current roles and a raw dump
+ *                        of all authorizations granted on the project.
+ *                        Read-only. Safe to run any time.
+ *
+ *   apply                Idempotently create the four canonical role keys
+ *                        (owner, user, platform_admin, platform_operator)
+ *                        if they are missing. Existing roles are left as
+ *                        they are; legacy keys (e.g. "customer") are NOT
+ *                        deleted by this command — see `migrate-auth`.
+ *
+ *   migrate-auth <user>  Drop every authorization the given user holds
+ *                        on the project and replace with a single
+ *                        authorization carrying ["owner"]. Use after
+ *                        `apply` to promote a legacy customer to the
+ *                        new role keys. Idempotent.
+ *
+ *   migrate-grants       Ensure every existing project grant on the
+ *                        OpenClaw Platform project includes both
+ *                        `owner` and `user` role keys. Without `user`
+ *                        in the grant, `CreateAuthorization` for an
+ *                        invited member returns Errors.Project.Role.NotFound
+ *                        (Bug 21). Idempotent: grants already containing
+ *                        both keys are skipped.
+ *
+ * Env vars (loaded from .env if you run with `node --env-file=.env`):
+ *   ZITADEL_ISSUER       e.g. https://auth.pieced.ch
+ *   ZITADEL_SA_PAT       PAT for pieced-sa (IAM_OWNER)
+ *   ZITADEL_PROJECT_ID   e.g. 367435120493199793

+ * -------------
+ * Customer-side: only an `owner` of the caller's org may change roles.
+ * `isCustomerOwner` is the right gate — `canMutate` would also accept
+ * platform users, but cross-org role mutation by platform staff
+ * belongs in ZITADEL Console with audited admin tooling, not here.
+ *
+ * Safety guards
+ * -------------
+ *   1. Self-demotion is blocked. An owner demoting themself to `user`
+ *      could lose access to /team and never come back. If the user
+ *      genuinely wants to step down they should promote a colleague to
+ *      `owner` first, then ask that colleague to demote them.
+ *   2. Last-owner demotion is blocked. Demoting the org's only owner
+ *      to `user` would lock the org out of all future role changes,
+ *      invites, and tenant requests. We count owners across the whole
+ *      member list and refuse if this change would leave zero.
+ *   3. The target must already have an authorization on the project.
+ *      A member without one — orphan, mid-invite race — has nothing
+ *      for `UpdateAuthorization` to update; we return a clear 409.
+ *
+ * The mutation itself is replace-not-merge: see
+ * `lib/zitadel.ts::updateAuthorizationRoles`. Passing `[role]` revokes
+ * any other roles the member happened to hold.

+ * BackLink — small "← Page" navigation cue that sits above a page's

+ * ---------------
+ * The pattern was originally written inline on /team and /dashboard/new

+ * That's wrong because `.accent-rule` (defined in globals.css) sets

+ * an inline-block H1 are both inline-level, and end up on the same
+ * baseline whenever there's horizontal room for them. The `mb-4` on the
+ * link does nothing because vertical margin between inline boxes
+ * doesn't push siblings to a new line.
+ *
+ * Solving it: this component renders the link as a block-level flex
+ * container with `w-fit` so it shrinks to its content (and its hover
+ * area doesn't span the gutter). The trailing block element below sits
+ * cleanly on its own line.
+ *
+ * Use it whenever a page has a back-link above an `accent-rule` H1.
