🎨 Palette: [Add keyboard navigation to interactive cards]

[Dev22603]

💡 What

Added keyboard accessibility (role="button", tabIndex={0}, onKeyDown handlers, and focus-visible styles) to the non-interactive motion.div elements that serve as clickable cards in the ProjectCard and ExperienceCard components.

🎯 Why

Previously, these interactive cards were only accessible via mouse clicks. Users relying on keyboard navigation could not focus the cards or trigger their click actions (opening modals or external links) using the Enter or Space keys.

📸 Before/After

(Visual verification media available in /home/jules/verification/screenshots and /home/jules/verification/videos)

♿ Accessibility

• Added role="button" and tabIndex={0} to allow the cards to receive focus.
• Implemented onKeyDown handlers to simulate clicks on 'Enter' and 'Space' presses (preventing default scrolling behavior for Space).
• Added logic in ProjectCard to ignore keyboard events originating from nested anchor (<a>) tags to prevent double-triggering.
• Added high-contrast focus-visible rings to provide clear visual feedback when a card is focused via the keyboard.
• Journaled the critical finding regarding keyboard accessibility on interactive non-button elements in .Jules/palette.md.
