/* ============================================================
   Calpiping Industrial Careers Portal — shared wizard stylesheet
   Deliberately NOT the same layout system as the sibling JP portal:
   no dark vertical step-rail + white card. Instead, a "spec sheet"
   composition — horizontal pipeline-style step tracker, a single
   centered worksheet panel with technical-drawing corner marks, a
   subtle blueprint grid on the page background, condensed industrial
   headings (Oswald), and monospace reference numbers (IBM Plex Mono)
   where JP used a decorative script/serif touch. Brand tokens are the
   real Calpiping Industrial colors: cyan #29abe2, charcoal #2e323c.
