/* =========================================================
   Sri Hari Tex — Design System
   Palette born from the product itself: charcoal like asphalt,
   amber like oil held up to light, steel blue for trust,
   rust for urgency. Signature element: the "level gauge" —
   an oil-dipstick-style fill bar used for stock levels and
   as an ambient motif, because that's genuinely informative
   here, not just decoration.
