   Shyaam Switchgear (P) Limited — Global Stylesheet  (v2 redesign)
   Design system: modern industrial — deep ink + refinery photography,
   safety-amber accent, geometric sans headings, generous whitespace.
   NOTE: never use the `padding` shorthand on a class that may be combined with
   `.container` in markup — use padding-top/padding-bottom longhand instead.
