IT11–IT13 mirror IT10 on the Linux platform branch, verifying:
- Xvfb workarounds coexist with SOCKS5 proxy mutation
- MSAA pin propagates through prefs translation on Linux
- _LINUX_GENERIC_FONT_FACTORS is prepended to per-font metrics
Tests use monkeypatch on sys.platform so they run on any host OS.
Verified green on Linux/WSL alongside the existing Windows tests.

Cover the Linux branches in prefs.py that previously had no tests
(font metrics, GPU spoofing, MSAA from profile, canvas noise mask
per renderer, WebGL extension preservation, Xvfb workarounds,
virtual_display no-op) and add construction smoke tests for
_LinuxVirtualDisplay. Also fix two host-platform-dependent tests
so the suite stays green on both Windows and Linux.

Final sweep adds unit tests for the modules left at 0% direct coverage
after Phases 1-9:
- launcher._tz_env: 7 tests covering the IANA -> POSIX mapping
including the Phoenix / Honolulu no-DST regression cases
- launcher._humanize_max_seconds, _default_context_kwargs: 11 tests
on the constructor-side helpers (no browser launch)
- _headless.make_virtual_display dispatcher + _WindowsVirtualDesktop
init/teardown: 8 tests (Linux dispatch branch covered without
spawning Xvfb, since __init__ does no I/O)
- async_api.InvisiblePlaywright constructor parity with sync: 8 tests
guarding against drift between the two APIs
Suite: 230 -> 264 passing. Pyramid stays clean: 243 unit / 12
integration / 9 e2e.

Five test the constructor only (seed handling, eager profile build,
fail-fast pin validation) and always run. Four spin up the patched
Firefox and exercise the full `with InvisiblePlaywright(...)` lifecycle,
gated on a locally cached binary so CI without the binary skips
cleanly. All 230 tests pass on Windows with the binary fetched.

Covers _accept_language, _font_metrics_for_platform, Windows GPU/MSAA
clearing, Windows canvas noise mask (intel path), Windows WebGL extension
clearing, timezone handling, extra_prefs overlay (add/delete/override/no-op),
dark-theme system colors palette, locale normalization, Xvfb-key absence on
Windows, virtual_display sandbox workaround, and seed-derived LAN IP.
Linux-specific branches are intentionally not covered in this commit per
scoping instruction; they remain available in the plan for a follow-up
pass when running on Linux.

Covers _validate_pin_key (all groups + negatives), _apply_pins_to_raw
(fonts list/tuple/typeerror, multi-pin, no-mutation, unknown-key guard),
and generate_profile (determinism, seed coercion, pin propagation through
to_prefs_dict, frozen-instance, dark_theme bool coercion, fonts list
roundtrip, int31 boundary). Includes a guard test that every dotted pin
key has a _PIN_TO_RAW mapping.

Covers classify_gpu (decision-table over 28 GPU strings inc. boundary
values for AMD Radeon number ranges), _screen_tier resolution
classification, derive_font_prefs / derive_font_whitelist coherence and
determinism, and the public Forge / sample entry points (locked
identity, key set, type correctness, seed determinism).
One plan deviation: the original plan claimed `AMD FirePro W7100` →
`workstation`, but the workstation regex requires a `Radeon` prefix,
so FirePro alone falls through to the `mid_range` fallback. Test
asserts the actual behaviour.

invisible-playwright: a patched Firefox 150.0.1 for browser-fingerprint
stealth, shipped as a Playwright-compatible Python wrapper.
* Sync + async InvisiblePlaywright launcher (firefox_user_prefs, virtual
desktop on Windows, SOCKS5 auth via patched nsProtocolProxyService)
* fpforge: Bayesian fingerprint sampler over GPU / audio / fonts /
screen / ~400 other navigator fields
* WebRTC stealth: srflx address swap, synthetic srflx fallback,
private-LAN host candidates. No real public IP leak via STUN.
* GPU sandbox fix for FF150 alt-desktop regression
* Bezier-curve mouse motion baked into Juggler
Targets Windows x86_64 + Linux x86_64. Binary fetched on first run from
GitHub Release "firefox-1".
