   Anti-orphan strategy:
   - Use ch units for max-width (character-based sizing prevents awkward line breaks)
   - text-wrap: balance for headings (distributes words evenly)
   - text-wrap: pretty for body text (improved wrapping algorithm)
   - orphans/widows properties prevent single words on lines
   - Center headings with auto margins for better visual balance
