/* ============================================================
   Strategic Orb Systems (STRATORB) — orbcore.io
   Production stylesheet — vanilla CSS, no build step.

   Register: monochrome private-bank. Pure white ground,
   near-black ink, a disciplined grey scale, hairline rules as
   the primary structural device. No colour accent, no
   drop-shadows, no hover "lifts" — calm, formal, institutional.
   Type: Fraunces (light, large optical size) for display +
   numerals; Inter for UI and body.
