   calc-hq.ca — site stylesheet
   Built from the design brief: navy-led and credibility-first, warmed by a soft
   canvas and generous whitespace. Trust leads (navy + structure); warmth is the
   canvas, spacing, and copy — not soft colours or playful UI.
   One family, one accent, muted throughout. No gradients, no neon.
