*   **Dot Grid Canvas:** An elegant, CSS-only radial dot-grid background overlaying the page.
*   **Typography:** The modern, high-readability sans-serif typeface `'Plus Jakarta Sans'` imported from Google Fonts.
*   **Glassmorphic Cards:** Translucent, backdrop-filtered cards with subtle glowing borders (`rgba(167, 139, 250, 0.08)`) and custom hover states.
