                    <h3>Can I start with a free trial?</h3>
                    <p>Yes. Creating an account starts you on the Draft Desk evaluation plan, so you can try the workspace before choosing a paid subscription.</p>
                </article>
                <article>
                    <h3>Can I subscribe without using the trial?</h3>
                    <p>Yes. Choose a paid plan from this page. If you are not signed in, PlotWeaver will ask you to log in before continuing to checkout.</p>
                </article>
                <article>
                    <h3>Can I change plan later?</h3>
                    <p>Yes. Signed-in users can manage subscription changes from the account subscription area.</p>
                </article>
                <article>
                    <h3>What happens to my work if I cancel?</h3>
                    <p>Your existing story data remains in PlotWeaver. Your account may return to the application-managed Draft Desk level after the paid subscription ends.</p>

                <article>
                    <h3>Is PlotWeaver suitable for a series?</h3>
                    <p>Yes. The higher plan limits are designed for authors managing multiple books, long arcs, and larger casts.</p>

                <article>
                    <h3>Do I need a credit card for the trial?</h3>
                    <p>The registration flow creates the evaluation workspace. Payment details are only handled when you choose a paid subscription through Stripe Checkout.</p>
