Lab: index
Instrumented spike pages. Every [data-lab-target] keeps data-count plus per-event and trusted counts. The autorun links make the engine spike run on load.
External canvas engines (score by eye)
No self-built fixture for these. Each has two links: the itch.io page (the game runs in a cross-site html-classic.itch.zone iframe after tapping "Run game") and the bare build as a top-level page.
- Unity WebGL (createUnityInstance loader): Muffin Clicker, itch.io page | bare build. Pass: a tap on the muffin at the center raises the "N MUFFINS" count at the top. itch.io shows "not designed to run on your device"; tap "Run game" anyway.
- Construct 3: Egg Clicker, itch.io page | bare build. Pass: a tap on the egg raises the click count under it. Landscape layout: rotate the phone, in portrait the bare build crops the egg off center.
