| The core, compiled to JavaScript 5ac0521 nandi 12h ago | 1 | // The web core, driven the way a browser drives it. |

| 4 | // this runs. What is checked here is the seam: that the JavaScript build |
| 5 | // loads, that a tree comes out as JSON, that an event goes in, and that a |
| 6 | // line fed in as if from a socket reaches the screen. Those are the four |
| 7 | // things that can break without a single Nim test noticing, because the |
| 8 | // desktop build does them through a different file. |
