/* Mory — base stylesheet.
   Waves 1–4 of MORY-STYLE-GUIDE.md §15.1 are landed: tokens, typography,
   the §7 component matrix (buttons incl. secondary/danger, inputs incl.
   select/date/checkbox, cards, focus ring), and the §9/§10 surface
   rhythm (review, ingest, daily, readiness, onboarding, account, login,
   marketing home). Wave 5 (toast/modal/tooltip/tabs/table/skeleton)
