Synapse scores real-world network quality from measurements you already have. It does not run speed tests — you collect the numbers; Synapse turns them into three metrics:

Scores are dimensionless. Use ScoreBand for a coarse qualitative reading (critical → excellent).

# Optional Serde support

fn main() {
    let data = NetworkData::new()
        .with_down_mbps(150.0)
        .with_up_mbps(40.0)
        .with_ping_ms(18.0)
        .with_jitter_ms(2.0)
        .with_packet_loss_percent(0.0)
        .with_rssi_dbm(-60.0)
        .with_noise_dbm(-90.0)
        .with_channel_width_mhz(40.0);

    if let Some(axon) = data.calculate_axon() {
        println!("Axon: {:.2} ({})", axon, ScoreBand::from_score(axon));
    }

    // Prefer try_* when you need structured errors:
    match data.try_vortex() {
        Ok(v) => println!("Vortex: {v:.2}"),
        Err(e) => eprintln!("Vortex unavailable: {e}"),
    }
}

• Wireless: Axon is the geometric mean of Vortex and Radiance.
• Wired (no RSSI/noise/width): Axon falls back to Vortex so Ethernet still gets a health score.
• If wireless fields are present but invalid (e.g. RSSI below noise), Axon returns an error instead of silently treating the link as wired.

try_vortex / try_radiance / try_axon reject non-finite values, negative speeds/latency/jitter, packet loss outside 0..=100, zero channel width, and RSSI below the noise floor. The calculate_* helpers return None in those cases.
