/* ==========================================================================
   Saishutsu — its own identity (owner, 2026-10-06), minimalist: a ledger.
   Paper and ink, one accent for money that can be followed, greys for the
   rest. Body in Atkinson Hyperlegible Next, figures in IBM Plex Mono.
   Still a Systems Atlas project, and still under its rules: no JavaScript,
   no inline styles, no third-party origins (see _headers).
   Class names are the generator's (build.py); "field--night" is the page's
   emphasis field, not a dark one.
