/* ═══════════════════════════════════════════════════════════════════════════
   OpenTuwa Studio — authentic Apple ecosystem design system.
   Three dedicated platform shells, one physics model:

     · macOS  — pointer shell  @media (hover:hover)(pointer:fine)
     · iPadOS — touch shell    @media (hover:none)(any-hover:hover) / hybrids
     · iOS    — phone shell    @media (hover:none)(any-hover:none)

   No shared breakpoint plumbing: every platform re-tunes its own tokens,
   chrome, touch targets, motion and overflow policy. Hover rules are
   gated to hover-capable devices so touch never sees stuck states.
   SF typefaces are resolved from the visitor's own Apple OS install;
   nothing is self-hosted, per Apple's font license.
