/* ==========================================================================
   Pono Petroleum — four dark design directions

     coastal   → Coastal Dark (default)
     basalt    → Basalt Run
     signal    → Pacific Signal
     fieldbook → Island Fieldbook

   Each direction owns both its design tokens and structural overrides. Shared
   components remain in base.css. Media wrappers accept either an image today
   or a video in the future without changing the surrounding layout.
