/* ── Document surfaces in dark: smart invert ──────────────────
   The Authentic document and the HTML preview render SPS/XSLT-styled
   content authored against white paper (explicit hex colors live in
   the SPS files). Instead of fighting authored styles, dark mode
   inverts lightness while preserving hue. The in-document editing
   chrome (ghost tags, validation tints — token-driven) re-pins the
   light token values so the inversion lands them back on dark-theme
   colors. Fixed-position popups (context menu, attribute asker) are
   siblings of these containers, so their positioning and normal dark
