   Indigo Forge — "Classical" design system + content-page patterns.
   Serif, gold-accented. Used by the five public content pages
   (Overview, Philosophy, Performance, Research, Copy Trading).
   Two themes: the dark default shares its palette with the research
   explorer (assets/app.css); `html[data-theme="light"]` restores the
   original light Classical look. assets/theme.js flips the attribute.
   The 4D explorer and the investor portal stay on app.css (dark tool chrome)
   and share only assets/chrome.css with these pages.
