   ORA Dental Implant — site design system
   --------------------------------------------------------------------------
   The visual language is "precision instrument": a cool titanium-and-ink
   palette for the surgical hardware, a warmer paper tone for the patient
   facing aligner brand, monospace for anything a clinician reads as data
   (references, torque, taper), and hairline rules instead of heavy borders.
   Everything is laid out with logical properties so the Arabic locale
   mirrors without a second stylesheet.
