Newsletter email is only validated server-side, after submit #3

🔎 Opened by loup from a user session recording.

The newsletter form performs no client-side or inline validation before the user submits. An invalid email is only flagged after a full server round-trip, at which point (due to the related form-replacement bug) the form becomes unrecoverable without a page reload. Adding inline pre-submit validation (e.g. using the HTML type="email" constraint or a JavaScript input listener) would catch the common case immediately and improve the overall subscribe flow.

Verified from the recording at 0:12: At 0:12 the error 'Invalid email address.' only appears after submission and server response, with no prior inline feedback visible; the form controls are gone, making the flow unrecoverable.
