   Sugi Predict — design system
   Ported from the Sugi Atlas Hugo theme (the "family" look): same tokens,
   typography, cards, pills, tables, header/footer chrome, dark mode.
   Hugo/Pagefind-specific machinery (TOC scroll-spy, manifest typeahead,
   hero variant switchers, per-category sitemaps) has been dropped — this is
   a FastAPI + Jinja2 app. New: confidence-band pills + stat-box for the
   predicted-targets domain.
