Thomas Hallock	d018b699c4	fix(flashcards): revert to simple delta positioning to prevent card jumping Reverted the complex rotation-compensated positioning that was causing cards to jump to the right of the viewport on click. The issue: The previous attempt to keep the grab point "stuck" to the cursor while rotating was mixing screen coordinates with container-relative coords, causing cards to teleport on pointer down. The solution: Use simple delta positioning (cursor movement from drag start) and let CSS handle rotation around the card center. While this means the grab point won't stay perfectly under the cursor as the card rotates, it's much better than cards jumping unexpectedly. The rotation still works - cards rotate based on grab point physics - but the positioning is now stable and predictable. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-10-21 11:21:49 -05:00

Thomas Hallock	50fc3fdf7f	fix(flashcards): correct pivot point to rotate around card center 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>	2025-10-21 11:18:04 -05:00
