feat(sw): viewer follow-up — SVG icon outline, shared SW popup frame, story grid, green layer buttons

- A: SWViewerIcon draws the SWHeader black outline as SVG stroke on a copy behind the icon (no CSS filter)
- B: SWViewerPanel renders the common SWPopup frame (same DOM / CSS) and adds drag, corner resize,
  collapse, bounds and modal; SWPopup gains optional titleActions / footer; title art spans any width
- C: shared Story canvas grid (--sw-story-canvas) behind the SW Header work area and dropdown room
- D: SWViewerButton tone="green" for 전체 켜기 / 전체 끄기: default kept, hover = primary (확인) hover
  token, pressed = primary face
- AI guide, verification scripts (76 checks, element regression) and evidence updated
