Detailed Description

Tests for Aleph::CA::Hex_Lattice and the hex coord helpers.

Scope:

• Round-trip for axial <-> offset (even-r and odd-r).
• Round-trip for axial <-> cube.
• Hex distance against ground-truth small cases.
• Concept conformance (Hex_Lattice satisfies LatticeLike).
• Hex_Neighborhood radial invariants.
• Hex Game-of-Life style B2/S34 rule by Bays: blinker pattern period-2 oscillation.
• Pixel mapping is finite and unique per coord.
• TikZ export contains expected fragments.
