/* [hidden] HARD GUARD (integrator, Guru_Universal 2026-08-11): the widget's JS shows/hides the
   panel and its inner rows (typing indicator, error banner, email-capture row, restart button)
   via the `hidden` attribute (`el.hidden = true/false`). Several of those elements ALSO carry an
   author `display:flex/…` rule below, which has equal-or-higher specificity than the UA
   `[hidden]{display:none}` and therefore DEFEATS it -- so a "hidden" panel stayed laid out at
   bottom-right on every page, silently intercepting clicks on page content beneath it (broke the
   myBugs "Add more details" click-path once Guru went omnipresent), and in kid mode the
   `hidden` email-capture row would still render (never ask a kid for PII). This one scoped rule
   makes the `hidden` attribute authoritative for every element inside the widget, restoring the
   JS's own show/hide contract. */
