Add TextAlign::WebkitCenter variant that centers both inline text and block-level children narrower than their container. The UA stylesheet now uses -webkit-center for <center>, matching real browser behavior where block children (like tables) are centered, not just inline text. The core mechanism is a post-layout shift in layout_block_children_vertical that repositions block children by (container_width - child_width) / 2. The shift_subtree_x helper recursively adjusts content origins, inline line boxes/fragments, and collapsed border segments. Guards prevent double-centering (auto-margin children), shifting table internals, and incorrectly shifting absolutely/fixed-positioned descendants.
