Geo-targeted extraction: locale, timezone, language

Rendered state depends on more than the URL. Sites branch on locale, timezone and language headers for currency formatting, RTL layout, region-specific fonts, and localized copy. Extracting without pinning those inputs captures whatever your local machine happens to report, which is rarely the market you're auditing. The --locale and --timezone flags set the browser's fingerprint before the page loads. --accept-language sets the header directly, independent of locale, for sites that branch on it without a full locale switch. Combine all three to reproduce exactly what a user in Helsinki, Tokyo, or São Paulo sees, and diff it against the default render to catch region-specific drift.
