+
+## 🩺 Health page
+
+The health page gives you a quick operational view of your instance without needing SSH first:
+
+- checks whether `config.json` exists and is writable by PHP
+- shows the current PHP version and whether `php-curl` / `php-xml` are loaded
+- tests each configured XMLTV source
+- tests each configured M3U playlist when present
+- shows response times, final URL after redirects, content type, and payload size
+- highlights XMLTV coverage for things like `category`, `sub-title`, `rating`, `date`, `desc`, logos, and stop times
+- gives you a rough XMLTV quality score per source
+- shows M3U stream counts, HTTP vs HTTPS split, and duplicate stream URLs
+
+By default, the page is protected by the same admin key as `setup.php`:
+
+```text
+http://guide.your-domain.com/health.php
+```
+
+If you enable demo mode with a `.demo` file, visitors can open the page without the key.
+
+For monitoring tools such as Uptime Kuma, GridTV also exposes a lightweight probe endpoint:
+
+```text
+http://guide.your-domain.com/health.php?format=probe
+```
+
+- returns HTTP `200` when the instance looks healthy
+- returns HTTP `503` when config, PHP extensions, or the first XMLTV source fail
+- returns compact JSON suitable for external monitoring
+
+If you prefer a plain text response:
+
+```text
+http://guide.your-domain.com/health.php?format=probe&plain=1

+## 🖨️ 24h export
+
+The export page builds a printable 24-hour TV guide from the current XMLTV source:
+
+- filter by source
+- choose the target date
+- restrict the export to a time window (`00h-24h`, morning, afternoon, evening, prime time)
+- limit the number of visible channels
+- choose between a readable card layout or a dense timeline
+- export to PDF via the browser print dialog
+- export to PNG directly from the page
+
+Public URL:
+
+```text

+
+This page is intentionally public so you can share a “TV guide sheet” with other people.

+<summary>Demo mode</summary>
+
+## 🧪 Demo mode
+
+If you want to expose your instance publicly without letting visitors modify it, create an empty `.demo` file at the project root:
+
+```bash
+touch /var/www/gridtv/.demo
+```
+
+When `.demo` exists:
+
+- `setup.php` becomes read-only
+- `health.php` can be viewed without entering the admin key
+- visitors can inspect the current configuration safely
+
+To disable demo mode:
+
+```bash
+rm /var/www/gridtv/.demo
+```
+
+> `.demo` is ignored by Git, just like `config.json`.
