pub const MAX_LSYSTEM_DEPTH: u32 = 7;Expand description
Hard clamp on L-system iteration depth, enforced at preset load. A branching
rule expands exponentially, so an unbounded max_depth would stall a preset
switch and blow the segment cap (ADR-0007 Risks). Curated presets stay well
under this; the turtle’s own segment cap is the second backstop.
