Module error 

Error type returned by the parser and the interpreter.

Every fallible API in this crate returns Result<T, ShapeError>. Variants cover three broad failure classes:

• Parse failures — ParseError carries a human-readable message from the nom parser, including the offending input span.
• Numeric / structural validation — InvalidNumericValue, EmptySplit, InvalidFloatingSize, SplitOverflow, NoFloatingSlots, UnknownCompSelector, OffsetTooLarge, InvalidRoofAngle, InvalidAlignTarget are raised when a parsed grammar would produce geometry that isn’t well-defined.
• DoS safety caps — CapacityOverflow and DepthLimitExceeded are returned when a grammar exceeds the engine’s bounded queue, terminal, op-count, identifier, or recursion limits rather than allowing unbounded resource use.
