Core Philosophy

A component library is not a random collection of buttons and modal components copied from tutorial repositories. A production component library is an ironclad, scalable UI contract between design and frontend engineering. Components must be structured with consistent anatomy, strict state matrices, accessible keyboard interactions, composable primitives, and 1:1 prop parity between Figma design components and React/Vue/Svelte code.

4-Step Component Library Architecture

Step 1: Component Anatomy & Structural Hierarchy

Deconstruct the Component Anatomy:
- Every complex component is composed of standard anatomical slots:
  - Container / Wrapper: Handles padding, surface background, border, and elevation.
  - Leading Element: Icon, avatar, or status badge.
  - Content Area: Label, description, children elements.
  - Trailing Element: Chevron, counter badge, action icon, or shortcut tag.
