Enum Block 

pub enum Block {
    Heading {
        level: u8,
        text: StyledText,
    },
    Paragraph(StyledText),
    Code {
        language: Box<str>,
        code: Box<str>,
    },
    Quote(Vec<Self>),
    UnorderedList(Vec<ListItem>),
    OrderedList {
        start: u64,
        items: Vec<ListItem>,
    },
    ThematicBreak,
    Table(Box<TableData>),
    Image {
        url: Box<str>,
        alt: Box<str>,
    },
}

A single renderable block produced by parsing.

Large variants (Table) are boxed to keep the enum compact (~56 bytes instead of ~72), improving cache locality during block iteration.

Immutable string fields use Box<str> to avoid the 8-byte capacity overhead of String — these values are never modified after construction.
