Widen height bound to 3-12 so the spec-named figlet fonts fit:
- Isometric1, Isometric2, Isometric3, Isometric4 (h=11)
- Calvin S (h=3)
Previously these were substituted with height-compliant alternatives
(Small Isometric1, Banner3-D, Henry 3D, Small Poison, Modular). Restoring
the spec-named fonts preserves the product intent: 4 distinct isometric
projections and the calvin-and-hobbes-style Calvin S font.
