/**
2+
* Client-side error + performance logger.
3+
*
4+
* Captures runtime errors, unhandled promise rejections, failed resource
5+
* loads, slow long-tasks, and a few page-load timings. Persists the most
6+
* recent events to localStorage (capped) so you can pull them back after a
7+
* page crash or slowdown.
8+
*
9+
* Logs are NOT shipped anywhere — they live only in the browser. To inspect
10+
* them:
11+
*
12+
* 1. Open DevTools console (errors print there in real time, prefixed
13+
* `[client-error]` / `[client-perf]`).
14+
* 2. Run `window.__getClientLog()` — returns the current buffer as an
15+
* array.
16+
* 3. Run `window.__downloadClientLog()` — downloads the buffer as a
17+
* JSON file you can attach to a bug report. Or visit any URL on the
18+
* site with `?downloadClientLog` to trigger the download
19+
* automatically.
20+
* 4. Run `window.__clearClientLog()` to reset the buffer.
21+
*
22+
* Nothing here is committed to git: logs only live in localStorage / Blob
23+
* downloads, and the *.log gitignore at repo root blocks any local files
24+
* you save from the download dialog.
