/* Invoice Pilot — design system
   Aesthetic: "Editorial Ledger / Warm Precision"
   - Warm paper neutrals (tinted with a hint of warmth, never pure gray)
   - Deep emerald as the single confident brand color (money/trust, not fintech cyan)
   - Amber as the sole accent for numbers/money
   - Fraunces (display, optical serif) + Spline Sans (body) — no Inter, no gradients
   - Ruled-ledger motif; restrained shadows; hairline borders
