Module peripheral_stealth 

Peripheral detection surface hardening.

Covers secondary browser detection vectors that build bot-confidence scores:

1. iframe innerWidth mismatch — ensures iframe inner dimensions differ slightly from the parent window (Kasada check).
2. Document visibility — forces document.hidden = false and visibilityState = "visible".
3. Camera / microphone device names — returns platform-appropriate fake device names with seeded random deviceId/groupId.
4. Port scan protection — blocks fetch and XMLHttpRequest to localhost on commonly-probed ports.
5. History length — overrides history.length to a plausible 3-8.
6. requestAnimationFrame timing — adds light per-frame jitter to prevent headless rAF timing detection.
7. PDF viewer — ensures navigator.pdfViewerEnabled reads true.

Example

use stygian_browser::peripheral_stealth::{peripheral_stealth_script, PeripheralStealthConfig};
use stygian_browser::noise::NoiseSeed;

let cfg = PeripheralStealthConfig::default_with_seed(NoiseSeed::from(1_u64));
let js = peripheral_stealth_script(&cfg);
assert!(js.contains("document.hidden"));
assert!(js.contains("History.prototype"));
