my_sign.html table-hex center — included via core/_partials/_table_hex.html
(hex_center). The lone SCAN SIGN button (the my_sign hex renders only when the
user has no saved significator; that {% if not current_significator %} gate
stays in my_sign.html).

<button id="id_scan_sign_btn" type="button" class="btn btn-primary">SCAN<br>SIGN</button>
