- Introduced `frames.py` to manage field complex calculations and their arrangement within node groups. - Added functionality to create and remove field frames based on node arrangements. - Developed `passages.py` to find unobstructed paths for connections around calculation frames. - Implemented `references.py` to route shared results on peripheral tracks, ensuring efficient distribution of outputs. - Created `sections.py` to reserve space for field calculations adjacent to geometry consumers. - Added `sources.py` to position shared calculation sources effectively beside their distribution channels. - Enhanced outline smoothing with `outline_smoothing.py` to adapt camera depth along original outlines.
