/* First-contact wizard — its own immersive skin, deliberately unlike the parchment voyages:
   near-black, neon, monospace. Self-contained: system fonts only (no web fonts), no external
   assets. The deck's bilingual convention is kept — every line carries lang="en"/lang="de"
   spans and the active one is shown by the root data-doc-lang attribute.

   Layout: the assistant speaks from ONE fixed slot (.hw-voice), always in the same place and the
   same big neon font — each line replaces the last, it is not a scrolling log. The current
   interaction (choices, input, the generated prompt) lives just below in .hw-controls. */

  /* The wizard's palette IS the Neon theme's tokens (--cvt-color-*, set by the neon-glass theme
     stylesheet the page loads). The literals here are only fallbacks for a bare file:// open with no
     theme stylesheet — they mirror the neon-glass values, so served and offline look the same. The
     assistant speaks in the glow, the user answers in the strong accent. */
