/*
  SEVRON — SUPPLY HOUSE
  -------------------------------------------------------------
  Design rationale:
  - Warm brown / burnt orange / marigold / cream are sampled conceptually from
    the supplied circular SEVRON logo, so the interface feels owned by the brand.
  - The previous layout has been replaced by an asymmetric commerce dashboard:
    a compact top rail, staged hero, irregular collection mosaic, catalogue console,
    split trade desk and integrated map/contact hub.
  - Dense modules are tuned around a 1085 × 1451 visual rhythm, while responsive
    rules collapse them into an app-like single-column experience on mobile.
