Adds three figures visualising the rainbow-orbit intersection from
tire_fiber_step2.tex (Observation rainbow):
k=6, T_1=(m=6, chord=(0,3), SP) vs T_2=(k=3, no chord, SR)
|S_1 ∩ S_2| = 6 = the S_3-orbit of (a,b,c,b,c,a)
Files:
- fig_rainbow_orbit.png: 6-panel grid showing all 6 orbit elements,
each as a hexagon coloured by the corresponding σ.
- fig_rainbow_pattern.png: abstract pattern abcbca on the shared
cycle γ with explicit position-class legend.
- fig_rainbow_setup.png: geometric setup — T_1 outside γ with its
antipodal chord (v_0, v_3) ∈ O_1, T_2 inside γ (a triangle), and
the orbit element σ = (1,2,3,2,3,1) shown on γ.
Adds experiments/draw_rainbow_orbit.py generator script.
