/* ---------------------------------------------------------------
   4Subtitles — shared waitlist survey (bottom sheet + casting dialog)
   Include on any page:
     <link rel="stylesheet" href="/shared/survey.css">
     <script src="/shared/survey.js" defer></script>
   Self-contained: every rule is scoped under #fs-sheet / #fs-cast and
   carries its own tokens, so it renders the same on dark and light pages.
   survey.js sets --fs-sheet-h on :root (height of the collapsed sheet);
   pages pad their content with var(--fs-sheet-h, 0px).
