/* ==========================================================================
   RabixAI — Shared Design System + Tool-UI Components
   --------------------------------------------------------------------------
   Aesthetic: editorial / financial-paper. Warm cream ground, near-black ink,
   ONE signal-orange accent. Fraunces (display serif), Hanken Grotesk (body),
   IBM Plex Mono (labels/eyebrows/numbers). Hairline rules + "worksheet"
   result cards that read like a calculation receipt.

   This single stylesheet powers EVERY page (homepage, trust pages, and all
   tool pages). Other agents building new tool pages should NOT add new CSS
   files — reuse the classes documented below.

   QUICK CLASS MAP (for agents building tool pages):
     Layout ......... .site-header / .site-footer / .tool-shell / .tool-layout
     Directory ...... .tools-grid / .tool-card / .tag
     Forms .......... .field / .field-row / .btn / .btn-primary
     Results ........ .result-card / .result-primary / .result-row / .result-note
     Explainer ...... .formula / .how-it-works
     Cross-links .... .related-tools
     Ads ............ .ad-slot (label is rendered automatically)
