   Harder III Consulting — Stylesheet
   Design language: industrial assembly line. Grounded in Lansing, MI's
   automotive manufacturing heritage (birthplace of Oldsmobile) — the firm
   is framed as precision-engineered consulting rather than civic, drafting,
   heritage, or organic registers used elsewhere. Equipment-plate panels,
   hazard-stripe dividers, and a gauge-dial hero mark replace ledgers,
   blueprints, seals, and river motifs.
   Palette: graphite/charcoal, saturated safety yellow, steel grey-blue.
   Type: Oswald (condensed, factory-signage display) + Roboto (body/UI).
