# Layer Fitness Enforcement

> Bind each layer invariant to a machine check — layer order declared once, placement properties barred from globals, class selectors barred from globals, literals barred where a token exists, no horizontal margin, all DOM through the factory, no inline style — run them as hard errors with no warn tier and no inline disables, and gate the push on a clean verdict.
