Struct HeadingSpec 

pub struct HeadingSpec<'a> {
    pub text: &'a str,
    pub level: u8,
    pub width_px: u32,
    pub height_px: u32,
}

Everything a heading’s geometry depends on: the text, the level (which picks the type scale), and the pixel box the raster fills. Deliberately free of colors and caret state so the same spec drives rasterization, hit-testing, and the fits check — a click must be answered by exactly the layout that was drawn.

Fields

text: &'a str

level: u8

Heading level, 1 or 2 — the only levels big enough to rasterize.

width_px: u32

height_px: u32
