Struct FrameDecoration 

pub struct FrameDecoration {
    pub width: Length,
    pub height: Length,
    pub pads: (Length, Length, Length, Length),
    pub elems: Vec<GraphicsElem>,
}

One block frame’s own decoration, captured at its natural size so a backend with no page grid can still draw it.

The graphics are BOX-LOCAL (origin at the frame’s bottom-left, y up) and span width x height, which is what lets a reflowable renderer scale them to whatever width the reader’s window gives the frame. fire_hooks records one per DecoId the first time that frame fires as a SINGLE fragment (decoS); a frame split across pages has no whole-frame drawing and records nothing.

Fields

width: Length

height: Length

pads: (Length, Length, Length, Length)

The frame’s own paddings, (left, right, top, bottom).

Three of the four are already visible in the flow — indent_left folds left into every contained line’s x offset, and the two vertical ones arrive as VertBox::FramePad — so a reflowing renderer needs only right, which nothing else records: the content is simply laid out narrower, and once the frame is redrawn at the reader’s own width a right-aligned line lands on its border.

elems: Vec<GraphicsElem>
