Redesign pair cards + add chip image highlight

- Complete CSS overhaul: refined typography, warm palette, 4:3 images, elegant chips
- Word chip click → popup badge with word + translation
- Object chip click → SVG bbox overlay dims image outside object bounds, draws amber outline
- All three card types (Sentence, YesNo, Word) updated
