/* Intentionally light-only for this launch. An earlier pass added a
   prefers-color-scheme override that only redefined a handful of CSS
   custom properties (--bg, --text, etc.) — but many components here set
   their own colours directly (the header's rgba(255,255,255,.96)
   background, .dropdown-panel's #fff, card borders/shadows tuned for a
   light ground, and more) rather than reading those tokens. The result was
   light-text-on-light-background in a system dark-mode browser, which is
   worse than no dark mode at all. Re-add this properly — auditing and
   re-theming every component against a real dark palette, then checking
   contrast — rather than re-enabling a partial override. */
