Ultra-lightweight floating Call & WhatsApp buttons for WordPress. Minimal, mobile-friendly, and easy to use.

== Description ==
Sticky Contact Lite adds minimal floating Call and WhatsApp buttons to your WordPress site.
- Lightweight (no DB tables, no external dependencies)
- Auto-injection site-wide or via `[sticcoli_contact]` shortcode
- Backward-compatible `[sticky_contact]` shortcode alias
- Mobile-only toggle
- Manual left/right positioning, suitable for RTL and LTR layouts
- Inline SVG icons with no external assets
- i18n-ready (Text Domain: sticky-contact-lite)

== Installation ==
1. Upload the plugin files to `/wp-content/plugins/sticky-contact-lite/`, or install the ZIP via Plugins → Add New → Upload Plugin.
2. Activate the plugin through the Plugins screen in WordPress.
3. Go to **Settings → Sticky Contact** and enter your phone/WhatsApp.
4. (Optional) Use shortcode `[sticcoli_contact]` where needed.

== Frequently Asked Questions ==
= Buttons don’t show up =
- Ensure you filled phone or WhatsApp in settings and clicked **Save**.
- If “Mobile only” is enabled, test on mobile or disable it.
- Ensure your theme calls `wp_footer()`.

= How to set WhatsApp link? =
- Enter only international digits without a leading local zero (e.g., `98912xxxxxxx`) or a full `https://wa.me/98912xxxxxxx` / `https://api.whatsapp.com/send?phone=98912xxxxxxx` link.

= Does the old shortcode still work? =
- Yes. `[sticky_contact]` is kept as a backward-compatible alias, but `[sticcoli_contact]` is recommended for new content.

= Can I use the shortcode while auto-inject is enabled? =
- Yes. If the shortcode is detected in the main post content, the plugin avoids auto-injecting a duplicate set of buttons on that page.

== Changelog ==

* Harden WhatsApp URL validation by allowing only `wa.me`, `www.wa.me`, and `api.whatsapp.com/send?phone=` formats.
* Normalize phone numbers to digits plus one optional leading `+`.
* Add backward-compatible `[sticky_contact]` shortcode alias.
* Add migration from the legacy `sticky_contact_options` option key.
* Prevent duplicate output when shortcode and auto-inject overlap; shortcode output takes priority.
* Enqueue the tiny frontend stylesheet whenever buttons are configured for reliable shortcode rendering in widgets, blocks, and page builders.
* Show admin settings errors when invalid phone/WhatsApp values are rejected.
* Improve settings registration with explicit type, default, and sanitize callback.
* Replace text glyphs with inline SVG icons.
* Improve keyboard focus styling, safe-area spacing, and reduce front-end z-index.

* Use unique, prefixed option key `sticcoli_options` and section IDs.
* Change shortcode to `[sticcoli_contact]` for uniqueness.
* Add frontend CSS file under `assets/css/frontend.css`.

= 1.0.1 =
* Align ownership metadata and headers/readme.
