Embed any free Calixo calculator into a WordPress post or page with a single shortcode.

== Description ==

Calixo (calixo.cloud) is a free calculator platform covering finance, health, math, engineering,
construction, and everyday life — 300+ calculators, no sign-up required.

This plugin adds one shortcode, `[calixo_calculator]`, that embeds any of those calculators directly
into a post or page as a live, interactive widget. The widget stays up to date automatically — it's
the same calculator running on calixo.cloud, not a static copy.

= Usage =

`[calixo_calculator path="finance/emi-calculator"]`

The `path` attribute is exactly the calculator's own URL path on calixo.cloud — copy it straight from
the address bar. Optional attributes: `height` (default 600), `width` (default 100%), `title`.

`[calixo_calculator path="health/bmi-calculator" height="500" title="BMI Calculator"]`

A usage guide is also available under Tools → Calixo Calculators in the WordPress admin.

== Installation ==

1. Upload the plugin files to `/wp-content/plugins/calixo-calculators`, or install the zip directly
   via Plugins → Add New → Upload Plugin.
2. Activate the plugin through the 'Plugins' screen in WordPress.
3. Add `[calixo_calculator path="..."]` to any post or page.

== Frequently Asked Questions ==

= Does this slow down my site? =

No calculator code loads until the embedded iframe itself loads (`loading="lazy"`), and nothing is
fetched from calixo.cloud until the visitor actually scrolls to it.

= Do I need an API key or account? =

No. Every Calixo calculator is free to embed with no account, API key, or usage limit.

= Can I style the embed? =

The `width` and `height` attributes cover the common cases. The embed itself follows the visitor's
system light/dark preference automatically.

== Changelog ==

= 1.0.0 =
* Initial release: `[calixo_calculator]` shortcode, Tools admin help page.
