+### Additional fields
+
+Depending on the HAR you feed in, the page object may also include:
+
+ * `fullyLoaded` — milliseconds from page start to the last asset finishing.
+ * `afterOnLoad` / `afterOnContentLoad` — request count, transfer size and content-type breakdown for assets fetched after `load` / `DOMContentLoaded`.
+ * `renderBlocking` — counts of `blocking`, `potentiallyBlocking` and `in_body_parser_blocking` assets (Chrome 92+). On sitespeed.io/browsertime HARs it also carries `recalculateStyle.beforeFCP` / `.beforeLCP` (elements touched + duration) for style-recalc work before each paint milestone.
+ * `googleWebVitals` — Core Web Vitals captured by sitespeed.io/browsertime.
+ * `cpu` — CPU events captured by sitespeed.io/browsertime or WebPageTest.
+ * `firstPartyRegEx` — the regex that was used to split first vs. third party (either the one you passed via `--firstParty` / `config.firstParty`, or the one auto-derived from the base domain).
