Term	Kind	Topic	What it is
Stale While Revalidate	pattern	Client Caching & Data Layer	Serving cached data immediately while fetching a fresh copy in the background, which makes an interface feel instant at the cost of a brief inconsistency.
Third-Party Script Governance Page as an Execution Environment, Vendor Script Review	practice	Frontend Security	Reviewing and constraining what executes on a page, because every third-party script runs with the page's full privileges - and each one is added individually while the aggregate determines the security posture.
Third-Party Weight Budget Tag Budget, Non-Application Script Allowance	metric	Web Performance Budgets	An enforced allowance for scripts the application build does not produce - count, bytes and main-thread time - with a named owner and a technical enforcement point, because these are the scripts a bundle-size …
Time to Interactive Gap	metric	Hydration Cost	The interval between a page appearing complete and actually responding to input, during which the user's taps do nothing.
UI Monorepo Strategy	practice	UI Monorepo Strategy	Whether frontend code lives in one repository or many — a trade between atomic change and independent release.
Web Performance Budget	practice	Web Performance Budgets	An enforced limit on payload size, resource counts or timing metrics, checked automatically so regressions fail the build rather than accumulating.
