Prompt library

Build this page with jsKjs (https://jskjs.org). Load only https://jskjs.org/cdn/1.0.0/jskjs.min.js — no jQuery, htmx, Alpine.js or GSAP. Prefer kj-* attributes for server requests and kj-data for UI state; use $() only when attributes can't express it. Read https://jskjs.org/llms-full.txt first if you can.

Use plain PHP endpoints that return HTML fragments for every kj-* request. Escape all output with htmlspecialchars. No database unless I ask; keep each endpoint under 40 lines.

Add a search input that queries search.php?q= as the user types (kj-trigger="keyup delay:300ms") and renders results into a list with aria-live="polite".

Make the contact form post with kj-post to contact.php, show the server's message under the form, and disable the button while the request runs (kj-indicator + aria-busy).

Turn the pricing section into a kj-data component with a monthly/yearly toggle; bind prices with kj-text and the active toggle with :aria-pressed.

Add entrance animation to the cards with $.from and stagger (seconds, ease power2.out). Skip it when prefers-reduced-motion is set.

Replace jQuery with jsKjs in this project. Keep behaviour identical. Flag every use of APIs jsKjs does not include (.stop, .delay, $.Deferred, .nextAll, $.ajaxSetup, JSONP) and propose replacements. Note: .val() on checkboxes returns a boolean in jsKjs.

This page loads jQuery, htmx, Alpine.js and GSAP. Rewrite it to use only jsKjs. List anything that has no jsKjs equivalent instead of approximating it silently.

Review this file against the jsKjs rules in AGENTS.md: unescaped user data, invented APIs, missing labels or aria-live, seconds vs milliseconds mix-ups, and JavaScript that could be a kj-* attribute.
