 - ([#14615](https://github.com/quarto-dev/quarto-cli/issues/14615)): Fix invalid `role="menu"` on the website navbar's collapse toggle button, flagged by axe-core (`aria-allowed-role`) and WAVE (`aria_menu_broken`) when the navbar collapses to the hamburger at narrow viewports.
 - ([#12116](https://github.com/quarto-dev/quarto-cli/issues/12116), [#4935](https://github.com/quarto-dev/quarto-cli/issues/4935)): Website sidebar section toggles are now `<button>` elements, so the keyboard can reach them and `Enter` or `Space` can operate them. Each toggle carries `aria-expanded`, and `aria-labelledby` names each disclosed list after its own section. The toggles no longer carry `role="navigation"`, which removed a spurious navigation landmark from every section.
+- ([#14774](https://github.com/quarto-dev/quarto-cli/issues/14774)): Fix missing keyboard focus indicator on the code tools button and on a website's sidebar toggle and sidebar search buttons.

+// button, the sidebar toggle, and the sidebar search button. Bootstrap's
+// .btn:focus-visible removes the native focus ring (outline: 0) and
+// substitutes a box-shadow that only the variant classes define, so these
+// buttons took keyboard focus with no visible indicator. Quarto restores
+// the browser's native ring with `outline: revert`.
+
+// Move focus with real Tab presses so the button matches :focus-visible —
