/* ═══════════════════════════════════════════════════════════════════════════
   SALSA CUBANA DALLAS — design system v2 · "Cinematic"
   Modelled on the craft of We Are Jealous (studiothis): monochrome UI, ONE
   sans, fluid clamp type scale, full-viewport panels, custom cursor,
   mix-blend-mode. Restraint — almost no keyframes.

   Deliberately gone: colour in the UI, cards, borders, hard shadows, emoji,
   tilts, marquees. The PHOTOGRAPHS keep their colour — they are the only
   colour on the page, which is what makes monochrome work.
