Lightweight seasonal effects (sakura, momiji, snow, fireworks) for WordPress sites — without sacrificing page speed.

== Description ==

**Season Particles** adds gentle seasonal effects — sakura petals, autumn leaves (momiji), snow, and fireworks — to your WordPress site, without slowing it down. A subtle way to surprise visitors and give your site a sense of season.

Cherry blossoms in spring, autumn leaves in fall, snow in winter, fireworks at New Year — all rendered with SVG and HTML5 Canvas for a lightweight, beautiful look on any device, without ever getting in the way of your content.

= Key features =

* **Four effects:** choose from sakura, momiji, snow, or fireworks.
* **Auto switching:** set a period (e.g. March 15 to April 15) and the effect will switch on automatically by date.
* **Fine-grained customization:** adjust quantity, speed, and size from the admin screen.
* **Display scope:** show on all pages, or limit to the front page only.
* **Lightweight design:** no jQuery — pure Vanilla JavaScript and the Canvas API.

== Installation ==

1. Upload the `season-particles` folder to the `/wp-content/plugins/` directory.
2. Activate the plugin through the **Plugins** menu in WordPress.
3. Go to **Settings → Season Particles** to configure effect type, quantity, speed, size, and display periods.
4. (Optional) Choose **Auto (follow period settings)** to switch effects automatically by date.

== Frequently Asked Questions ==

= The effect is not showing. What should I check? =

Make sure you've selected an effect other than **None** on the settings screen. If you've chosen **Auto**, confirm that today's date falls within one of the configured periods. Also clear your browser cache.

= Does it affect page speed? =

The impact is negligible. The plugin uses HTML5 Canvas with `requestAnimationFrame` for optimized rendering, keeping browser load very light.

= Can I show effects only on the front page? =

Yes. In the settings screen, set **Display scope** to **Front page only**.

== Screenshots ==

1. Admin screen for configuring effect, quantity, speed, and schedule.
2. Sakura effect in action.
3. Snow effect with a soft drop shadow.
4. Vivid fireworks effect.

== Changelog ==
