# LibrePortal — agent notes

## Verify WebUI changes visually before marking them done
After changing anything user-visible in the WebUI (`containers/libreportal/frontend/`),
confirm it actually renders correctly — syntax checks and type-correctness don't
catch layout or visual regressions.

The maintainer's dev environment provides a headless screenshot helper, `lp-shot`,
that captures a WebUI route (or a single element, via a trailing CSS selector) to a
PNG for review:

```
lp-shot /admin/system                       # full route -> /tmp/webui-shot.png
lp-shot /admin/system /tmp/x.png 12 ".sys-strip"   # just one element, crisp
```

Use it (and read the PNG) to self-check UI work instead of assuming it looks right or
asking the user to look. Skip it for purely backend/non-visual edits. If `lp-shot`
isn't present, fall back to asking the user for a screenshot.
