/* =============================================================================
   ILFIRIN — "DATUM" brand system
   A clinical-precision instrument. Blue-grey near-black, signal-blue accent,
   cool-green for pass/ok. IBM-Plex-Mono tabular labels + a faint lab-notebook
   hairline grid. Every accent is rationed; nothing glows that doesn't carry a
   reading. System fonts only — no external fonts, no JS dependency.

   Ported verbatim from concept-datum.html (palette, type, signature gesture)
   and expanded to dress an entire multi-page site.
