/* Frequency & Sonic Sanctuary — the poster layout
   Mahal's Sonic Sanctuary poster as the page: engraved gold title, the
   tri-colour tagline, the Solfeggio Resonance (couple + list), the medallions,
   the instrument, and the founder block. Loaded last, so it wins over the
   base layers without !important.
