 ### Changed
-- Playwright pin moved to `>=1.55,<1.62` (was `>=1.55,<1.56`). The `firefox-18` binary rebases onto Firefox 151, which is what the latest Playwright (1.61) pairs with, so 1.61 now drives the binary natively - no more pinning to an older client. Both ends of the range were tested against the new binary (full browser suite on 1.61; drift-free protocol on 1.55). `scripts/playwright_pin.txt` -> 1.61.0.
+- Playwright pin moved to `>=1.55,<=1.61.0` (was `>=1.55,<1.56`). The `firefox-18` binary rebases onto Firefox 151, which is what the latest Playwright (1.61) pairs with, so 1.61 now drives the binary natively - no more pinning to an older client. Both ends of the range were tested against the new binary (full browser suite on 1.61; drift-free protocol on 1.55). The upper bound is capped at the exact latest tested version (1.61.0) rather than an open `<1.62`, so a Playwright release we have not validated against this binary cannot be pulled in and break a fresh install; the cap moves forward deliberately, once a new version is tested. `scripts/playwright_pin.txt` -> 1.61.0.
 
 ### Added
 - `timezone="auto"`: the browser timezone is auto-derived from the egress IP. By default (no explicit timezone) it ALWAYS resolves — from the proxy egress when a proxy is set, otherwise from the host's own public IP — so the zone can never disagree with the IP (the classic `timezone_mismatch` signal). An explicit `"Area/City"` is the only way to force a specific zone. On failure: with a proxy the launch raises (no silent host-TZ fallback behind a foreign proxy); without a proxy it falls back to the host TZ so a transient lookup can't break the launch.
