   PK Tech Gurus — pktechgurus.pro
   Design system. One stylesheet, no build step, no framework.

   Palette rationale: the company both *advises* on IT (SIC 62020/62090) and
   *repairs* the hardware itself (SIC 95110). Deep petrol-teal carries the
   engineering half; a warm copper hairline — the colour of a soldered joint —
   carries the craft half. Restrained, dark, and quiet rather than loud.
