Frontend (SSR, Jinja2) for CRM on FastAPI - strictly according to the technical specifications, without SPA

There is a ready backend CRM on FastAPI (Python 3.12).
Roles implemented: admin / supervisor / manager, authorization, RBAC, CSRF, security middleware, API contracts.

It is necessary to implement the zero stage of the frontend (Stage 0) strictly according to the technical specifications.

Frontend — server-side rendering (SSR):

* Jinja2 templates
* minimal vanilla JavaScript
* no React / Vue / SPA

The project is engineering-focused, emphasizing architecture, security, and predictable UI behavior.

The backend is already implemented. The architecture is fixed.
The frontend does not contain business logic, only display and interaction with the API.

What needs to be done:

1. Implement SSR pages:

* auth: login, TOTP setup
* dashboard by roles (admin / supervisor / manager)
* employee lists
* user cards
* system error pages (403 / 404 / 500)

2. Implement a common frontend layer:

* unified JS API client (fetch is prohibited outside of it)
* correct handling of 401 / 403 / 422 / 500
* safe-redirect (next)
* CSRF (double submit)
* breadcrumbs
* role-based sidebar
* global UI states: loading / empty / error

3. Ensure security requirements:

* CSP compatibility (no inline-script, onclick, etc.)
* correct handling of cookies and CSRF
* no bypassing backend restrictions

4. Testing:

* minimal set of e2e tests (Playwright)
* checking basic user scenarios

Technical requirements (mandatory):

* SSR (Jinja2 or similar), no SPA
* FastAPI backend (already ready)
* Vanilla JS (modules)
* Understanding of HTTP statuses and UX errors
* Experience with role-based interfaces
* Attention to technical specifications and details
* Willingness to strictly follow the architecture

---

What NOT to do:

* SPA / React / Vue
* Rewrite the backend
* Simplify requirements
* Add fields, logic, or UI "at your discretion"

---

Work format:

* Fixed volume (Stage 0)
* Stage acceptance
* Direct communication with the project architect
* Technical specifications — the only source of truth
