   When .menu-open is first added, the sub-menu flashes at its stylesheet
   default position (left:100% from style.css ul ul ul) for one frame before
   positionSubmenu() fires in requestAnimationFrame.  On narrow viewports
   left:100% pushes the flyout off-screen right.
   Override to right-anchor (right:0; left:auto) so the flyout stays within
   the viewport even before JS sets the final position.
   Specificity 0,5,0 beats style.css .main-navigation ul ul ul (0,1,3).
   positionSubmenu() overrides this safely via inline styles:
