/* ============================================================
   Lockstep Mini App -- Stage 2: shared design-kit applied
   Replaces the earlier terminal aesthetic (dark brass/ink) with the
   white/silver canvas + trustworthy blue + teal secondary system from
   /Users/bob/Projects/lockstep-design-kit/index.html. Tokens, component
   patterns (cards, buttons, data rows, elevation) are lifted directly
   from that kit -- this file adapts them to a single-column mobile app
   shell rather than the kit's own wide desktop-sidebar layout.
