What separates a lab from a hub
A lab measures something. It reads your controller through the browser, or times your
keyboard, or reads your screen, and turns that into a sentence about the game you play —
not a percentage. A hub is a verified list of that game's default bindings with routes to
the right general tool, which is genuinely useful and is not the same thing.
Both are marked above so you know which you are opening. The five hubs without a lab are
not neglected; they are waiting for a question that game asks and a browser can answer.
Where no honest measurement exists, this site would rather link a tool than invent one.
What a browser can and cannot prove
Every lab states its own boundary on its own page, and they are real boundaries. A browser
reads your controller, your keyboard, your pointer and your screen. It cannot see the game,
your frame rate inside it, or the server you are playing on. Where a figure would need
something the browser cannot reach — a publisher's unpublished threshold, an internal
sensitivity constant — these pages say so instead of printing a precise-looking number.
