- Heading hierarchy: H1 bumped to 1.125rem with letter-spacing to
distinguish from H2 (both were 1rem). Margins normalized to 0.5rem
baseline rhythm.
- List items: increased spacing from 0.125rem to 0.25rem for readability.
Remove paragraph margins inside list items (Tiptap wraps li content
in <p> tags which inherited 0.5rem margins).
- Nested lists: bullet style progression (disc → circle → square) and
numbering progression (decimal → lower-alpha → lower-roman).
- Blockquotes: tighter paragraph spacing inside, nested blockquotes get
lighter border for depth indication.
- Inline code: border-radius uses semantic --radius-sm token.
