🎨 Typography & Heading Hierarchy

This is a comprehensive note designed to visually verify the prose typography, block spacing, and syntax highlighting across light and dark themes.

Good design is as little design as possible. Less, but better — because it concentrates on the essential aspects, and the products are not burdened with non-essentials.

Sub-heading: Interactive Elements & Code

Inline code elements look like const greeting = "Hello, world!" and links seamlessly transition like Dolf’s Home without layout jumps.

”Simplicity is about subtracting the obvious and adding the meaningful.”
— John Maeda, The Laws of Simplicity

1. CodePen Embed (CSS & JS Animations)

2. React & TypeScript Live Component Playground

3. Embedded Go Playground & Runtime

Lists & Structured Data

Here is an unordered list of frontend principles:

• Clean Separation of Concerns: Isolating business logic from presentation.
• Performance Budgeting: Sub-second First Contentful Paint.
• Accessibility (a11y): Accessible semantic structure for all users.

And an ordered pipeline workflow:

1. Lint and type-check codebase.
2. Run automated unit test suite with 100% coverage.
3. Validate visual regression snapshots across responsive viewports.
