+ * PATCH (secure-snapshot): content protected by an isSecureTextEntry canvas
+ * (per-view capture protection, e.g. expo-privacy-sensitive) is stripped from
+ * the render-server snapshot RNSScreen takes for JS-driven pops, so the user
+ * sees the hidden fallback (the GrowthHack butterfly) during the transition.
+ * The capture-exclusion flag is only consulted for layers INSIDE a captured
+ * subtree, so a snapshot rooted BELOW the flagged canvas still includes the
+ * content.
+ *
+ * By the time setViewToSnapshot runs, the screen's children are already
+ * unmounted (only the pixels survive on the render server), so the secure
+ * subtrees must be captured HERE - before the transaction's mutations apply,
+ * while the subtree is intact. The overlays are stashed on the screen view
+ * and composited over the main snapshot in setViewToSnapshot, each re-wrapped
+ * in a fresh secure canvas so real captures (screenshots/recordings) taken
+ * during the transition still exclude them.
