/*
  Momo — product page.

  Ported from the Claude Design project's `Momo Landing.dc.html`, on the Mosey
  design system's "Cozy Dusk" tokens. The source is a desktop-fixed canvas
  styled inline; this keeps its proportions, colour and type exactly, and adds
  the responsive behaviour a shipped page needs.

  The site's CSP is `script-src 'none'`, so everything here — including the
  five-mood hero rotation — is CSS. See README for what that costs.
