/* ==========================================================================
   Finscale — shared stylesheet for finscale.dev / docs.finscale.dev /
   api.docs.finscale.dev. Single source of truth; page-local CSS ≈ zero.

   Design direction: banking-grade restraint. Near-white paper, deep ink,
   hairline borders instead of shadows, radius ≤ 6px, one cobalt accent used
   sparingly, letterspaced small-caps overlines, tabular numerals, dark code
   panels. No gradients, no soft-shadow card grids, no violet.
