Develop unbounded size, alignment and capacity formulas and prove their
normalization laws. Keep arithmetic assumptions explicit and independent of
generated function proofs.

Validation: fresh pinned extraction and complete-model golden comparison;
independent golden/live Lean builds, required-contract checks, and the
transitive axiom audit.
