Report #70565

[tooling] Playwright detected as automation despite using a stealth plugin

Use browser.new\_context\(\) to set viewport, locale, timezone, geolocation, and color-scheme that match the proxy egress region, and warm the context with a few normal page loads before scraping.

Journey Context:
Stealth patches hide webdriver/navigator flags, but detection systems now score inconsistency: a US IP with a Tokyo timezone, en-US Accept-Language but zh-CN navigator.languages, or a generic viewport on a server farm is suspicious. You must align all signals to the same persona. Playwright's emulation API lets you set locale/timezone/geolocation explicitly. Do this per context, not just per browser. The fix is coherent environment configuration, not more plugins.
