Core Strategies

1. Content First: Ensure the HTML structure is semantic and readable without any CSS.
2. CSS-First Layout: Use Modern CSS (Grid/Flexbox) for layout before adding JS interactivity.
3. Core Functionality: All critical paths (navigation, forms) must work with pure HTML/CSS.
4. Enhanced Experience: Add "luxury" features (animations, async loading, complex UI) only after the core is solid.
