Handler converts axis/angle integers to floats; worker stores target axis obj+0x1f8 and angle obj+0x208 and builds target matrix obj+0x12c. gfx_object_apply_transform_channels samples current axis/angle linearly on shared start obj+0x34 and composes T(-anchor)*scale*rotation*translation*T(anchor).

+- **summary:** (handle)(period_ms)(axis_x)(axis_y)(axis_z) — configure cyclic rotation. Worker stores period obj+0x228, start obj+0x214=0, and float axis obj+0x244; each frame uses integer degrees floor(((now-start)%period)*360/period). gfx_object_composite right-multiplies this separately anchored transform after the one-shot scale/rotation/translation product, so cyclic rotation also rotates the translation vector.
