 * The share flow (upload, share created, share download) and today's rework of it, plus the
 * settings/admin buttons and sections reworked alongside it — all changed since the last browser
 * run (148ff38) without one. tests/Browser/SealShareTest.php, FrameTest.php and
 * SettingsAndAdminTest.php already cover the flow's existing behaviour; this file adds what that
 * rework introduced and does not re-assert what those already do (the copy-to-clipboard toast, the
 * dragover burst, the QR code's fill and PNG export).
