🚀 Overview

Zak – Multi Purpose Mobile Web App (PWA) is a clean, production-oriented Progressive Web App template designed for
building installable, offline-capable mobile experiences with web technologies. Whether you’re launching a
content app, mini-eCommerce, booking flow, or a dashboard, Zak ships with responsive UI blocks, route scaffolding, and PWA
essentials so your site behaves like a native app across Android, iOS (Safari), and desktop browsers.

Experience (E): Inspired by real client rollouts—city guides, micro-CRMs, and event apps—Zak focuses on
fast first paint, offline navigation, and app-like interactions (splash screen, home screen icon, full-screen mode).
This accelerates delivery without compromising Lighthouse scores or accessibility.

✨ Key Features

• 📱 Installable PWA: Web App Manifest with icons, name/short_name, theme/background colors, standalone display mode.
• 🛰️ Offline Support: Production service worker with pre-cache + runtime caching strategies (Cache-First / Network-First).

• 🧭 Routing: Client-side navigation with fallback to server routes; 404/Offline pages included.
• 🔔 Push-Ready: Optional Web Push boilerplate (VAPID) for engagement campaigns.
• 🌍 i18n & RTL: Localization structure, number/date formatting, RTL stylesheet variant.
