Native <dialog aria-modal> cheatsheet: showModal()/close() bridge, close button focused on open, eight grouped <kbd> rows (nav/edit/utility), an autosave footer line, and a reduced-motion-guarded fade. Closes on Esc, backdrop click, and the close button; "?" while open is a no-op. Adds the shortcut_close_panel i18n key. 8 component tests. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
