Struct HeadlessOptions 

pub struct HeadlessOptions {
    pub width: u32,
    pub height: u32,
    pub prefer_software: bool,
}

How to build a headless Renderer for capture (Plan 0013).

Deliberately carries no tier: Renderer::new_headless is Tier::Floor by construction, which is what keeps every golden baseline byte-reproducible (ADR-0045). A capture at another tier goes through Renderer::new_headless_tiered, where the choice is written at the call site and cannot be reached by forgetting a field.

Fields

width: u32

Offscreen render width in pixels.

height: u32

Offscreen render height in pixels.

prefer_software: bool

Force a fallback (software) adapter — WARP on DX12 — so captures rasterize identically across machines. Tests want this on.
