/* ============================================================================
   Solutions of Today — platform design system.
   Derived from William's UI mockup (Claude design console artifact, 2026-09-26).

   This is a NEW stylesheet rather than an edit to sot.css. sot.css carries the
   old teal + Cormorant identity and is still what the retired pages
   (/setup/, /tools/, /custom-build/, /discovery/) render with. Editing it in
   place would have broken every one of them mid-pivot. When those pages are
   retired or rebuilt, sot.css goes with them and this becomes the only one.

   Values are read from the mockup, not approximated.
