//! WS4b Tier-2 (updated WS5-prep): software-rendered shapes land the expected
//! pixels. Headless, no GPU. Uses the normalized `render_frame`, so probes are in
//! natural top-left coordinates with the drawn colors (no BGRA / Y-flip
//! compensation — `render_frame` handles both).
#![cfg(feature = "software_renderer")]
