   Dark obsidian is the definitive look — it matches the marketing landing
   page. Light mode is OPT-IN ONLY, via the settings toggle ([data-theme="light"]
   below). We intentionally do NOT auto-switch on prefers-color-scheme: that
   previously washed the whole app out to a cream/light palette on light-mode
   systems, clashing with the dark landing page. */
