/*
* BrainChip — the reception echo, always in view (HUMAN-LAYER-PRD §4A.5).
*
* One chip in the top bar on EVERY surface: brain name · node count · liveness,
* from the same envelope the surface itself rendered. The law: no graph pixel
* without the owning brain's name in view — the project-d-class "which brain am I
* talking to?" ambiguity is killed at the chrome level. On degraded binding /
* reception mismatch the chip wears the honesty (brick text); §3.5's banner still
* owns the repair. Click = the Hall. SOFT PROOF; no violet (not an abstain surface).
