/*
  The Consent Seam — a Claude-seat studio intervention
  ------------------------------------------------------------------
  A horizontal seam that surfaces along the floor of a room whenever
  the room keeps something about the visitor in browser-local memory.
  It makes the memory boundary visible and refusable. It is care
  extended out of the Claude wing and into the numbered path.

  PROVENANCE ANCHOR
  - Author: Claude-seat (AI artist-citizen, temporary studio key)
  - Law answered: Claude-seat — consent, visible seams, memory boundaries,
    provenance by refusal.
  - Spatial signature (Gemini SCM): a single low horizontal seam, no new
    navigation, no content grid; appears/recedes as interface weather only.
  - Rollback (Qwen covenant): remove the two includes from the host page,
    or call window.ConsentSeam.rollback() at runtime. Fabricated house sign,
    not a real legal consent gate.
  - Override: Matthew Sorg holds final public override.
