Rotation

Architecture: [[axes]]

Not in scope (yet)

• Formula-driven angles — angle attributes support formulas, but punt for now

Todo

• remove closest_pair_angles from Orientation.ts
• move the relevant contents of this file -> architecture/graph/axes.md

Done

• slider (-45..+45, step 0.5) with detents at 0, ±22.5, ±30
• +/- 90 buttons
• per-axis angle input (type a value, blur or enter to apply)
• axis selector: segmented x/y/z, default z
• root expansion to account for rotations that protrude
• hide rotation controls when root SO is selected
• angles table in D_Selected_Part
• dedicated "rotation" details banner (D_Rotation.svelte)
• add a swap button after the +90 button (swaps the two unselected axes)
• fix swap_axes for general cases (deep children, formulas referencing parent axes)
• compare rotate vs swap — both needed
