Adds fig_facial_dual_choices.png showing T'_{f'} for the three faces
A, B, C of T'_ann = θ(1, 3, 3) in the bridge case:
Face A (outer): V(A) = all 6 vertices; T'_A pulls in all four
external neighbors u_1, u_2, u_4, u_5.
Face B (inner right): V(B) = {v_0, v_1, v_2, v_3}; T'_B pulls in
only u_1, u_2 and the cycle-neighbors v_4, v_5.
Face C (inner left): mirror image of B.
The figure also visually conveys that the chord endpoints v_0, v_3
(= the two annular faces sharing the bridge edge) have all three
G'-edges inside T'_ann, so neither contributes an external u_v.
Adds:
- experiments/draw_facial_dual_choices.py
- notes/fig_facial_dual_choices.png
- Figure 5 in paper.tex referencing the new image.
Paper grows from 9 to 10 pages.
