/* =====================================================================
   The Historical Hall — Styles
   Mood: a Skadoodle discovery room — deep purple/violet magic, ancient
   ink-black stone, and warm gold kept as the accent for artifact/history
   value (torches, buttons, age markers). Ancient, but signature-Skadoodle
   and a little magical, not a formal museum lesson.
   Kid-friendly but not babyish. Respectful of the history.
