* Code Blue — an error-log reader, as an OpenStation app. |
| 4 |
* |
| 5 |
* This file is the window: title, size, icon, the title-bar Refresh |
| 6 |
* button, the ⋯-menu Clear row, the state schema, the server actions, |
| 7 |
* and the DATA the browser paints from. The body itself is rendered |
| 8 |
* in the browser by `code-blue.os.ts` — a function of that state and |
| 9 |
* data — so range, search, sort, legend and expand never wait for a |
| 10 |
* request; only reading a different source, refreshing and clearing |
| 11 |
* round-trip. The log model (discovery, tailing, parsing, clearing) |
| 12 |
* lives in `log-reader.php`. |
| 13 |
