- Add StoryNotice and a withSWNotice decorator so every visible SW Story
shows the common notice above its title; non-SW Stories are unaffected.
- Align the SW Header overview with the common SW Story page layout, let the
preview Stage fill the available width and keep inner scroll on narrow screens.
- Rename SW/Footer to SW/하단 명령어바 (sidebar title only, Story IDs fixed via
id: "sw-footer"), drop the top SWHeader from its preview and lower the
workspace height bounds by the removed 49px.
