Bezier mouse curves, per-character typing with mistype simulation, smooth micro-step scrolling, idle micro-movements between actions. Supports both sync and async Playwright APIs. Patches page, frame, context, browser, and Locator class methods. Two presets: 'default' (normal speed) and 'careful' (slower, deliberate). Configurable via HumanConfig dataclass / interface with full override support. Bug fixes (from PR review): - fill()/clear(): platform-aware select-all (Meta+a on macOS, Control+a elsewhere) - sync Locator check()/uncheck(): wrap mouse_move in RawMouse-compatible object - resolve_config(): raise error on unknown preset name - Lazy-load human.config via __getattr__ in __init__.py - humanPreset typed as 'default' | 'careful' literal union - browser.newPage() patches implicit context Tests: Python 36/36, JS Vitest 34/34, visual Python 17/17, JS 13/13
