I need a custom WordPress theme that immediately evokes the clean, minimal feel of the Astro documentation site. I’m building everything with Elementor, so the template you create must drop straight into Elementor’s Theme Builder and render exactly like https://docs.astro.build/en/getting-started/—just scaled down and tightened so the spacing feels more compact. For this first phase I only need the homepage, but it still has to behave like a true documentation layout. That means a persistent left-hand sidebar that shows an active state as I scroll, a top search bar that filters results instantly, and a light-to-dark toggle that works without a full-page reload. On desktop, tablet, and mobile the layout should re-flow gracefully; the sidebar can collapse into an icon drawer on smaller screens as long as navigation remains obvious. Please build with modern semantic HTML and utility-first CSS (Tailwind is fine) and keep any JavaScript lean—just what’s required for the search interaction, the collapsible menu behavior, and the color-mode switch. Performance, accessibility (WCAG compliance), and sound SEO markup are non-negotiable; Google Lighthouse should report green across the board when you hand it over. Deliverables • Elementor-ready homepage template (PHP + inline Tailwind or compiled CSS) • Sidebar navigation powered by WordPress menus, with active-link tracking • Algolia-style instant search (vanilla JS or lightweight library) • Light/dark mode toggle using prefers-color-scheme and localStorage fall-back • Mobile-first responsiveness, validated for the latest Chrome, Safari, Firefox, and Edge • Final hand-off pack: theme files
