shinalokandClaude Sonnet 5 d212451fe0 add habit goal-period difficulty and habit formation research notes
Ground the 21-day habit myth in actual research (Lally et al. 2010) and let
users pick a target period (21/66/254 days or unlimited) matching that
study's easy/median/hard automaticity timelines when creating a habit,
with progress shown on the habits list.
