    ⚠️ Small text: 14px may be hard to read on mobile. Consider 16px+.

    ✅ Good hierarchy: Clear distinction between headlines and body text.

    ✅ Smart font loading: Using font-display: swap prevents invisible text during load.

    ✅ Protected text on images: Using gradient for readability.

    ⚠️ Cramped layout: 15 elements lack adequate spacing.
