/* ============================================================================
   ideagram studio — design system
   ============================================================================

   The STUDIO's own visual language. Deliberately not Spora's.

   Spora's system (living in each of its pages) is a night garden: blue-black,
   teal glow, whispered lowercase type, everything soft-edged. That's the
   product's voice, and it should stay the product's alone. A studio that also
   makes film and sound for other brands needs a shell that doesn't look like
   one of its own products wearing a different hat.

   So this one is the opposite temperament: warm near-black, paper-white type,
   one loud accent, hard edges, big display type, generous space. Editorial
   rather than atmospheric.

   Only `index.html` (and future studio pages) should link this. Anything under
   /spora keeps Spora's own styling.
