   OIL AI DDR — DESIGN SYSTEM
   Drilling operations console.

   Design principles, translated from the OIL AI brand voice:
     - Data leads, chrome recedes. Navigation is dark and quiet so the
       report surface is the brightest thing on screen.
     - Colour carries meaning, never decoration. Warm hues (amber/red)
       are reserved for operational state; the cool accent marks only
       what is active or selected.
     - Instrument, not landing page. Hairline borders and tight radii
       instead of gradients, soft shadows and pastel washes.
     - Numbers align. Tabular figures on every data surface so columns
       of depth, ROP and mud weight scan vertically.
