E-commerce Components Proposal

Version: 1.0 Created: December 2025 Status: Proposal Author: Development Team

---

Overview

This document proposes a comprehensive set of reusable Jinja macro components for the shop frontend. These components will standardize the e-commerce experience across all store shops while supporting store-specific theming via CSS variables.

---

Design Principles

1. Store Theming - Use CSS variables (var(--color-primary)) for brand colors
2. Mobile First - Responsive design starting from mobile
3. Performance - Lazy loading, optimized images, minimal JS
4. Accessibility - WCAG 2.1 AA compliant
5. Consistency - Same UX patterns across all shops
