   Bix Premium Layer
   Additive interaction polish shared by the marketing homepage and
   the /inbjudan signup flow. Assumes each page already defines its
   own dark-first palette; only hardcoded values below are the ones
   that must stay consistent regardless of which :root is active
   (ivory F0EDE8 / sage 7BAF96).
   Fully inert unless premium.js opts the page in (pointer:fine,
   hover:hover, no prefers-reduced-motion) — see premium.js gating.
