   DashView — Widget Builder, professional layer (v2.19)
   Loaded after css/accent-sync.css (dashboard.html) and on share.html.
   Everything here reads the live theme tokens (--signal, --on-signal, --paper, --ink-*, --line*, --st-*),
   so it follows the accent, light/dark and the chart colour scheme. No fixed black anywhere.
