Cadova 1.2.1

Improvements

• Models that contain many polygons build noticeably faster. On a large real-world model, CPU time dropped by about 30%.
• Transformed geometry uses less memory during a build, typically 2–12% less at peak.
• The Cadova skill for coding agents now covers idiomatic model structure, parts, and Helical clearance holes, so agents write code that reads more like hand-written Cadova.

Fixes

• Customizer pages no longer draw stray edge lines across flat or smoothly curved faces.
