/* =====================================================================
   DESIGN PLAN
   Layout: left-aligned editorial column (max 1120px) over a full-bleed
   3D scene on the home page; sub-pages open with a short header and go
   straight to content. One orchestrated load sequence per page, motion
   otherwise answers the reader's own actions.
   Color: deep petrol ground, amber signal accent, cyan for data,
   with a cool pale-slate light theme.
   Type: Bricolage Grotesque for display, IBM Plex Sans for reading,
   IBM Plex Mono for data and code.
