One change, three different 'after' figures in three places — each one true in its own frame and misleading without it. The fix is labels, not consistency.

— The same change produces different 'after' figures per frame of reference.
— A figure without its frame is a rumour with a decimal point.
— Every recorded number on the site names what it measures.
Three afters
A change shipped and three pages printed three numbers: the route's own JavaScript before and after, the total for a cold visit, and the embed's payload. All three were measured, all three moved, and no two agreed — because they measure different things. The label is what makes a number true.
The convention
Every before/after pair on this site now names its frame: 'JS on a component detail page', 'JS on a route that renders no demo'. The changelog entry is the contract, the build report is the evidence, and the harness holds the pair together.
