Fixed issue where cards appeared to pivot around the grab point in viewport space instead of rotating around their own center. The problem: When dragging, the card would stay "pinned" at the grab point in screen space, making it rotate around that viewport location. The solution: As the card rotates, calculate the rotated grab offset and reposition the card so that: 1. The grab point stays under the cursor 2. The card rotates around its own center 3. The visual result feels like the card is "stuck" to your finger Implementation: - Convert rotation angle to radians - Apply 2D rotation matrix to grab offset vector - Calculate card center position: cursor - rotated grab offset - Convert center position to top-left for CSS translate positioning This creates the natural feeling of grabbing and spinning a physical card by its edge. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
