Design System

This document defines the planned design-system scope. It does not implement UI yet.

Purpose

The design system should give Shop3 a consistent storefront foundation without adding unnecessary framework weight or visual lock-in.

Planned Areas

• Typography.
• Colours and tokens.
• Spacing.
• Buttons.
• Forms.
• Cards.
• Grid and container rules.
• Mobile behaviour.

Principles

• Mobile-first.
• Accessible by default.
• Performance-aware.
• Compatible with OpenCart templates and common modules.
• Tokens before repeated hardcoded values.
• Defaults over excessive configuration.

Before Implementation

Before major UI implementation, document token names, responsive rules, and component states. UI PRs should include desktop and mobile screenshots.
