# Iteration 005 — Camera mouse-look + quest education polish

## What shipped
- Added right-click / middle-click drag mouse-look to the 3D scene camera.
  - Drag horizontally rotates the view like directional camera arrows.
  - Drag vertically adjusts pitch.
  - Mouse wheel zooms camera distance.
  - Context menu is suppressed while using right-click look.
- Updated controls help in the side panel:
  - Right/middle-click drag to rotate camera.
  - Wheel to zoom.
  - Arrow keys still orbit the view.
- Added richer Hermes Agent education metadata to quest definitions:
  - `lesson` explains the Hermes Agent concept each quest teaches.
  - `payoff` explains why the player should care.
- Upgraded journal quest cards to show:
  - Hermes lesson block.
  - Why it matters block.
  - Clearer quest state pill: completed / selected automatically / unlocks after prior quest.

## Why
Eric wanted desktop recording to feel better and requested mouse camera movement like directional arrows. He also wanted each quest to be easier to view/select/complete and to teach more about Hermes Agent. This pass directly improves recording controls and makes the journal a stronger in-game docs/onboarding surface.
