/* ============================================================
   BIGFOOT TRUCK BEDS - design system v1 (10/18/26)
   Shares Bigfoot DNA (construction yellow + satin black, Barlow
   Condensed display) but reads as its own division: steel grey
   surfaces, plate texture, sharp corners, zero gradients-for-show.
   Theme: DARK, locked. Radius system: all-sharp (0) except 2px on
   inputs. One accent: --gold.
