## 설명

Arvexa Performance Overlay shows a small pill in the corner of every page — for 
administrators only. Click it and you get a live panel with everything that matters
about the page you are looking at:

 * **Server** — PHP generation time, SQL query count and total time, peak memory,
   number of enqueued scripts and styles, total size of autoloaded options, and 
   the lifecycle phase that ate the biggest share of PHP time.
 * **Components** — the cost of every plugin and theme on this page: SQL queries
   and time on the server side, requests and transferred bytes on the asset side.
   The answer to “which plugin slowed us down” in one glance.
 * **Network** — TTFB, request count, transferred bytes.
 * **Rendering** — LCP (and _which element_ it is), CLS, INP, DOM node count, long
   tasks. Official Web Vitals thresholds, color-coded.
 * **AJAX / REST** — every same-origin admin-ajax, wc-ajax and REST call timed as
   it happens.
 * **Slowest queries** — the top queries with timings.

#### How it works

 * Per-query plugin attribution uses the `log_query_custom_data` filter and a backtrace
   scan — no core hacks, no db.php drop-in.
 * The plugin never enables or changes `SAVEQUERIES`. To collect query timings, 
   a site administrator may explicitly add `define( 'SAVEQUERIES', true );` to `
   wp-config.php` before the “That’s all, stop editing!” line.
 * Visitors are never affected: for anyone without the capability the plugin adds
   no assets, no queries and no output.
 * Add-ons can extend the panel via the `arvexa_performance_overlay_data` PHP filter
   and the `window.ArvexaPerformanceOverlay` JS API.

#### Arvexa Performance Pro

Deep diagnostics live in the Arvexa Performance Pro add-on: full hook timeline, 
server cost of every AJAX/REST call (X-Arvexa-Performance header), remote HTTP tracking(
see what your shipping/payment APIs cost), WP_Query explorer with SQL and EXPLAIN,
per-plugin drill-down cards, layout-shift attribution per element, and performance
history with before/after comparison when a plugin is installed or updated.

## 설치

 1. Upload the `arvexa-performance-overlay` folder to `/wp-content/plugins/`, or install
    through the WordPress plugin screen.
 2. Activate the plugin.
 3. Open any page of your site while logged in as an administrator — the Arvexa Performance
    Overlay pill appears bottom right. Click it to expand the panel.
 4. Reload once more to get SQL timings and the per-plugin breakdown (see FAQ).

## FAQ

### Why is the per-plugin SQL breakdown empty on the first load?

The plugin never enables `SAVEQUERIES`. To collect per-plugin query timings, add`
define( 'SAVEQUERIES', true );` to `wp-config.php` before the “That’s all, stop 
editing!” line, then reload the page.

### Does it slow down my site?

For visitors — no: without the capability nothing is collected, enqueued or printed.
For the logged-in admin the plugin adds one fast SQL aggregate. Query logging is
active only when the site administrator has explicitly enabled `SAVEQUERIES`.

### Who can see the overlay?

Users with the `manage_options` capability. Change it with the `arvexa_performance_overlay_capability`
filter.

### Does it work in the admin area?

Yes — the panel is available on both frontend and admin pages. Browser metrics like
LCP are most meaningful on the frontend.

### Is any data sent anywhere?

No. Everything is measured and displayed in your browser on your own site. Arvexa
Performance Overlay makes no external requests.
