Outline: restyle the share page and the printed / Word outline

- Read-only share page: a calm paper-toned page rendered natively (no
  iframe), with outline tabs, Print / PDF, numbered points with accent
  numerals, type tags, notes and verse quotes; works on phones
- Printable / PDF page restyled to match (serif, hanging numerals, tidy
  spacing, footer)
- Word outline restyled: eyebrow + title block, bold main points, accent
  numerals, set-off verse quotes, tidy margins
