Template rendering

<form method="post">
    {% form.register_form %}
    <button type="submit">Sign up</button>
</form>

Automatically renders: all fields, labels, validation errors, CSRF token, and JS scripts.

<form method="post">
    {% csrf %}
    <div class="row">
        <div class="col-6">{% form.register_form.username %}</div>
        <div class="col-6">{% form.register_form.email %}</div>
    </div>
    {% form.register_form.password %}
    <button type="submit">Sign up</button>
</form>

{% if register_form.form_errors %}
    <div class="alert alert-danger">
        {% for msg in register_form.form_errors %}
            <p>{{ msg }}</p>
        {% endfor %}
    </div>
{% endif %}

form_errors → Vec<String> — errors not tied to a specific field (e.g. "Invalid credentials"). errors → map { field_name: message } — per-field errors + global errors under the global key.
