-Formulation implementations for continuum mechanics.
-
-This file contains implementation methods for continuum formulations.
-- Abstract types: continuum/abstract.jl (AbstractFormulation, AbstractContinuumTheory)
-- Concrete types: continuum/types.jl (FullThreeD, PlaneStress, etc.)

-# TODO: Add formulation-specific implementation methods here
-# Examples:
-# - Material property transformations for different theories
-# - Strain-displacement matrix construction
-# - Theory-specific assembly helpers
