Reduce activation energy of habits to near-zero for fallback

Why This Is a Principle

Grounded in Directed Attention as Depletable Resource (cognitive resources deplete under stress), Behavior occurs when three elements converge simultaneously (behavior requires motivation, ability, and prompt), and Behavior follows the path of least resistance due… (behavior follows least resistance). The principle prescribes designing low-activation fallbacks specifically because disruption attacks the ability component of the MAP model. It is actionable, general across habits, and derived rather than foundational.
