Snowfall

Simple easy-to-use and easy-to-set-up lightweight plugin for snowfall effect on your site.

Season Spark loads tasteful front-end particle effects and lightweight visual overlays. The plugin’s implementation and admin UI provide the following behavior and options (exactly as implemented in the plugin):
<ul>
<li>Included effects: <code>christmas</code> (snow/twinkles), <code>halloween</code> (ghosts/pumpkins + fog overlay), <code>valentines</code> (hearts + confetti), <code>newyear</code> (occasional fireworks bursts), <code>easter</code> (eggs & bunnies, occasional large egg drop), <code>thanksgiving</code> (falling leaves + occasional turkey popup), <code>independence</code> (fireworks + occasional flag/spark bursts), <code>diwali</code> (lights/diya sparkles + occasional diya popup), <code>hanukkah</code> (menorah sparkles + occasional menorah popup), and <code>generic</code> (custom graphics: rain/stars/bubbles or an uploaded background).</li>
<li>Per-effect configuration: <code>enabled</code>, optional <code>schedule</code> with <code>start</code>/<code>end</code> dates, <code>density</code>, <code>speed</code>, and <code>color</code> for effects that use color (the admin shows color pickers only for effects that accept color).</li>
<li>Custom Graphics support: the <code>generic</code> effect can use an uploaded background (<code>custom_bg</code>) and an uploaded custom cursor image (<code>custom_cursor_image</code>). When <code>custom_bg</code> is set the plugin creates a lightweight animated background element instead of particles.</li>
<li>Custom Cursor support: when a per-effect <code>custom_cursor</code> is enabled the front-end will attempt to use a provided <code>custom_cursor_image</code> or bundled SVG image as an overlay cursor (implemented by the public JS initializer).</li>
<li>Accessibility: the plugin respects the user’s <code>prefers-reduced-motion</code> setting, supports a site-level <code>motion_reduced</code> admin toggle, and prints a small per-user motion toggle (stored in <code>localStorage</code>). When reduced motion is active, visual initialization is skipped.</li>
<li>Performance: only enabled effects have their per-effect JS files enqueued; the plugin localizes <code>seasonSparkSettings</code> and <code>seasonSparkImages</code> for front-end initialization and ships the <code>tsparticles</code> bundle under <code>assets/vendor/tsparticles/</code>.</li>
</ul>
Admin and developer features (as implemented):
<ul>
<li>Admin pages: top-level “Season Spark” menu with the subpages <code>Effects</code>, <code>Settings</code>, and <code>For Devs</code>.</li>
<li>Settings: global toggles (load particle library, reduce motion) and default density/speed values; the Effects page exposes per-effect controls, schedule toggles, density/speed inputs, color pickers for color effects, and WP Media-based selectors for custom background/cursor on the <code>generic</code> effect.</li>
<li>Developer filters present in the code: <code>seasonspark_get_registered_effects</code> (modify the list of effects), <code>seasonspark_settings_for_js</code> (filter settings passed to front-end JS), and <code>seasonspark_images_for_js</code> (filter the image mapping sent to JS).</li>
</ul>
Notes:
<ul>
<li>Default activation: by default only the <code>valentines</code> effect is enabled on activation.</li>
<li>Assets: effect scripts, images and styles are bundled under <code>assets/</code>; the plugin enqueues only enabled effect scripts to keep the front-end lightweight.</li>
</ul>
