Release 1.3.0: unified front-end UI shell

 follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/); versions
 correspond to git tags (`vX.Y.Z`) and `nodejs/package.json`'s `version`.
 
+## [1.3.0] - 2026-07-26
+
+### Changed
+- **Unified the front-end UI shell across the three theta42 apps.** `views/top.ejs`, `views/bottom.ejs` and `public/lib/js/app-base.js` are now byte-identical in sso-manager-node, proxy and jump-host, so the apps look and behave the same and a shell change lands in one edit per repo instead of three divergent ones. Everything that differs between the apps moved into a new `nodejs/utils/ui.js`, exposed to every render as `ui` via `app.locals`: nav items and the groups that may see them, footer repo/license/docs/Terms links, favicon, the profile and post-logout targets, and whether the update banner exists at all.
+- **One nav-gating model everywhere.** `app-base.js` reveals `.group-required-<cn>` elements for each group the current user is in, read from `GET /api/user/me`. sso-manager-node reports LDAP DNs in `memberOf` and the OIDC clients report CNs in `groups`; both normalise to CNs client-side, and the clients' effective-rights `isAdmin` flag is exposed as a synthetic `admin` group — so one gating model covers a group-based provider and boolean-admin clients without either app learning the other's response shape.
+- **`GET /api/user/me` is fetched once per page load and cached** (`app.auth.loadUser`). The nav, per-view `forceLogin` and every group-gated element read that one promise instead of issuing their own request.
+- `app.auth.isLoggedIn` is dual-mode: it returns a Promise **and** invokes an optional node-style callback, so the async and callback call styles both work against one shared `top.ejs`.
+- `app.auth.forceLogin` no longer uses `$.holdReady` (removed in jQuery 4). An unauthenticated user is redirected to `/login?redirect=<path>`; group requirements are still enforced, and `logOut` now only clears the session, leaving the destination to the caller (`ui.logoutRedirect`).
+- Dependency alignment across all three apps: `jquery` `^4.0.0` and `ejs` `^3.1.10`.
+
+### Fixed
+- **`app.api.delete` dropped its callback when called by `formAJAX`.** `formAJAX` always passes the serialized form as the second argument, so a DELETE-method form's callback landed in the data slot and never ran. `delete` now accepts both `(url, callback)` and `(url, data, callback)`.
+- **`app.api.post`/`put` referenced an undefined `callback2`** and threw when handed a non-function callback. Both are now dual-mode Promise/callback.
+- **The login page's "reveal the card once we know you're logged out" branch threw** (`Cannot read properties of null`) whenever the logged-in check answered before the parser reached that element — which it always did without a stored token. It now runs on DOM ready.
+- **`logInRedirect` on the legacy `/login/<path>` form kept only the path.** The OIDC provider routes an unauthenticated authorization request through `/login/oauth/authorize?client_id=…&state=…`; dropping the query there loses the entire authorization request. The suffix form now preserves its query string.
+
+### Added
+- `.group-required { display: none }` in `public/css/styles.css`, the base rule the shared gating model reveals against.
+- `#spa-shell` dropped its inline `margin-top`; `styles.css` already sets it and the shared shell adjusts it when a banner is shown.
+
+### Verified
+- Browser-verified against a full theta-env stack (sso-manager + proxy + jump-host): every top-level page renders with a clean console; nav gating is correct for admin and non-admin; `forceLogin`'s onboarding and group gates fire; `val.js` blocks a weak password and accepts a strong one through a real form submit; the DELETE-method forms work; and the OIDC login round trip (authorize with PKCE -> login -> consent -> callback -> token fragment) completes on both OIDC clients.
