   `hidden` must always win.

   The browser's own [hidden] { display: none } lives in the user-agent sheet, so ANY author
   rule that sets `display` unconditionally outranks it — `.card { display: flex }` silently
   defeats `<div class="card" hidden>`. That has been patched one class at a time all over this
   file (search "[hidden]" — there are ~100 of them, plus three separate comments explaining the
   same surprise). This single rule makes the attribute authoritative everywhere instead, which
   is what `hidden` is supposed to mean, and stops the bug reappearing in new components.

   Placed last, and marked !important, so it also beats same-specificity !important display
   rules (e.g. .pagination-controls) that would otherwise win on source order. The only rules
   that legitimately reference the attribute in the other direction use :not([hidden]), which
   simply stops matching once the element is hidden — so they are unaffected.
