/*
Shared design system for every page except the dashboard (index.html,
which has its own darker/denser app-chrome styles) and landing.html
(which stays fully self-contained since it also carries the 3D hero
script and shouldn't be touched just to dedupe CSS). Every marketing/
account page -- pricing, FAQ, terms, privacy, how-it-works, login,
signup, admin -- links this file so the site reads as one system.
