1//! Story: solid-color redaction (M-MASK.5 / AUT-23).
2//!
3//! Two redaction variants side-by-side over the same screen-capture
4//! backdrop: a hard rectangle (left) and a rounded rectangle (right).
5//! Both are filled with opaque black — the cinematic "this content
6//! is sensitive, full stop" treatment.
