/* CM Solutions — design system
   Layout: calm sections on warm paper; content column 72rem, reading measure ~38rem.
   One signature diagram (the journey of a unit, drawn like the pump's segmented
   pressure display) and one physical object (the hand-filled Ready Seal card).
   Palette: deep teal for structure, near-black ink, ballpoint blue only where a
   person writes by hand. Light only, by decision (Sept 2026). Type: serif display, hyperlegible sans body, hyperlegible
   mono for unit IDs, times, and codes. */
