			Welcome to Deka DOM Elements (dd<el> or DDE) — a lightweight library for building dynamic UIs with
			a declarative syntax that stays close to the native DOM API. dd<el> gives you powerful reactive tools
			without the complexity and overhead of larger frameworks.
		`),
		el("div", { className: "callout" }).append(
			el("h4", t`Key Benefits of dd<el>`),
			el("ul").append(
				el("li", t`No build step required — use directly in the browser`),
				el("li", t`Lightweight core (~10–15kB minified) without unnecessary dependencies (0 at now 😇)`),
				el("li", t`Natural DOM API — work with real DOM nodes, not abstractions`),

		el(h3, { textContent: t`The 3PS Pattern: Simplified architecture pattern`, id: "h-3ps" }),
		el("p").append(T`
			At the heart of dd<el> is the 3PS (3-Part Separation) pattern. This simple yet powerful approach helps you
			organize your UI code into three distinct areas, making your applications more maintainable and easier
			to reason about.

					el(code, { src: fileURL("./components/examples/introducing/3ps.js"), page_id }),
				)
			)
		),
		el("p").append(T`
			The 3PS pattern separates your code into three clear parts:
		`),
		el("ol").append(
			el("li").append(T`
				${el("strong", "Create State")}: Define your application’s reactive data using signals
			`),
			el("li").append(T`
				${el("strong", "React to Changes")}: Define how UI elements and other parts of your app react to state
				changes
			`),
			el("li").append(T`
				${el("strong", "Update State")}: Modify state in response to user events or other triggers
			`)
		),

		el("p").append(T`
			By separating these concerns, your code becomes more modular, testable, and easier to maintain. This
			approach ${el("strong", "is not something new and/or special to dd<el>")}. It’s based on ${el("a", {
				textContent: "MVC", ...references.w_mvc })} (${el("a", { textContent: "MVVM", ...references.w_mvv })}),
			but is there presented in simpler form.
		`),

		el("div", { className: "note" }).append(
			el("p").append(T`
				The 3PS pattern becomes especially powerful when combined with components, allowing you to create
				reusable pieces of UI with encapsulated state and behavior. You’ll learn more about this in the
				following sections.
			`),
			el("p").append(T`
				The 3PS pattern isn’t required to use with dd<el> but it is good practice to follow it or some similar
				software architecture.
			`)
		),

		el(h3, t`Getting Started`),
		el("p").append(T`
			There are multiple ways to include dd<el> in your project. You can use npm for a full development setup,
			or directly include it from a CDN for quick prototyping.
		`),
		el("h4", "npm installation"),
		el(code, { content: "npm install deka-dom-el --save", language: "shell", page_id }),
		el("h4", "CDN / Direct Script Usage"),
		el("p").append(T`
			Use the interactive selector below to choose your preferred format:
		`),
		el(getLibraryUrl, { page_id }),
		el("div", { className: "note" }).append(
			el("p").append(T`
				Based on your selection, you can use dd<el> in your project like this:
			`),
			el(code, { content: `
				// ESM format (modern JavaScript with import/export)
				import { el, on } from "https://cdn.jsdelivr.net/gh/jaandrle/deka-dom-el/dist/esm-with-signals.min.js";

				// Or with IIFE format (creates a global DDE object)
				// <script src="https://cdn.jsdelivr.net/gh/jaandrle/deka-dom-el/dist/iife-with-signals.min.js"></script>
				const { el, on } = DDE;
			`, language: "js", page_id }),
