Summary
Adds a Favorites flow to the Languages grid:
Heart (❤️) button on each language card to toggle favorite
“View Favorites” button near the “Programming Languages” header
Persisted via localStorage so favorites survive refresh
Accessible: keyboard toggle (Enter/Space), aria-pressed, focus outline
How it works
On page load, favorites are read from localStorage (codeshub:favorites).
Each card has a heart button that toggles the language’s favorite state and updates storage.
The “View Favorites” button filters the grid to only favorite languages (toggle on/off).
If localStorage is unavailable, the feature still works for the session (no crash).
Manual Testing
Click ❤️ on 2+ languages → icon fills and stays filled after reload.
Click View Favorites → grid shows only those; click again to see all.
Keyboard: Tab to the heart, press Space/Enter to toggle; aria-pressed flips true/false.
DevTools → Application → Local Storage → confirm codeshub:favorites JSON array.
Issue
Closes #379.
