//! All-figures data generator (fig_01 – fig_62).
//!
//! Combines the original 20 figures (from generate_figures.rs) with 20 new
//! Phase-4 figures. Every data point is produced by running the real
//! `dsfb-rf` engine; no hand-crafted numbers are used.
//!
//! Each Phase-4 scenario is anchored to one of three public RF datasets:
//!   • DARPA SC2 / Colosseum (adversarial spectrum sharing, PAWR/NSF)
//!   • NIST POWDER-RENEW (city-scale OTA, University of Utah)
//!   • IQEngine / ORACLE USRP B200 (hardware diversity captures)
//!
//! NON-CLAIM STATEMENT (applies to figures 21-40):
//! All phase-4 data is produced from structurally-representative synthetic
//! residual sequences whose signal model is documented in the dataset
//! references above.  Actual dataset access requires portal authorisation.
//! Numeric claims (detection lead-time, false-alarm rate) are bounded to
//! these specific scenario parameterisations and do not constitute
//! operational deployment validation. See paper §L5.
//!
//! Usage:
//!   cargo run --features std,serde --example generate_figures_all
//!
//! Output: ../dsfb-rf-output/figure_data_all.json
