## 説明

**Flex Maintenance** is part of the FLEX plugin suite from **FLEX LLC** (https://
flexible.am/). It puts a public splash in front of the website while you build or
repair it. Login and wp-admin stay available. Logged-in administrators always see
the real site. Use Preview splash to check the design.

 * Coming soon, under construction, or maintenance page types
 * Optional start and end schedule in the site timezone
 * Countdown when a future time is set
 * Bypass by extra roles, secret link, IP allowlist, or public paths
 * Three local templates (centered, split, minimal), logo, background, accent, and
   social links
 * Preview from admin and an admin-bar badge when the splash is on
 * Block bots and crawlers while the splash is on (Recommended, on by default)
 * Purges Flex Cache when the splash turns on or off

Admin CSS and JavaScript ship with the plugin. The public page does not load Tailwind,
Google Fonts, or any other remote stylesheet. No remote calls. No telemetry.

#### Privacy

Flex Maintenance does not log visitors, IPs, or user agents. It does not send data
to FLEX or any third-party service.

**IP allowlist** (optional): addresses you type on Settings are stored in the WordPress
options table. The plugin compares them to `REMOTE_ADDR` only. It does not store
visitor IPs.

**Secret bypass cookie** (optional): if someone opens your secret link, a 7-day 
HttpOnly cookie (`flex_maintenance_ok`) is set so they can see the real site. The
cookie holds the preview token. It is not used for analytics.

**Preview** (administrators only): **Preview splash** opens the public page with
a nonce so you can check the design without logging out.

#### Limitations

 * This is a splash page, not a landing-page builder, form plugin, or analytics 
   tool.
 * Only one full-page splash is shown. It does not hide wp-admin or the login form.
 * Fast page caches (including Flex Cache) are purged when settings change. The 
   splash itself is not stored in Flex Cache.

## インストール

 1. Upload the `flex-maintenance` folder to `/wp-content/plugins/`, or install the 
    zip via **Plugins  Add New  Upload Plugin**.
 2. Activate **Flex Maintenance**.
 3. Go to **Flex Maintenance  Design** and save the splash copy.
 4. Go to **Flex Maintenance  Settings**, choose the page type, then enable the splash.
 5. Open the site in a private window (logged out) to confirm visitors see the splash.

## FAQ

### Can visitors still log in?

Yes. `wp-login.php` and wp-admin stay open. If Flex Website Security uses a custom
login slug, that path stays open too.

### Who sees the real site?

Logged-in administrators always see the real site. You can also allow extra roles,
IPs, paths, or share a secret bypass link. Use Preview splash to check the design.

### What HTTP status does it send?

Maintenance sends 503 with Retry-After. Coming soon and under construction send 
200. The splash is never stored by Flex Cache after a purge.

### Does it load CSS from a CDN?

No. Templates are local CSS. There is no Tailwind runtime and no Google Fonts.

### What happens when I uninstall?

Deleting the plugin removes its settings and the cache-state flag. It does not change
your theme or other plugins.
