The face of learn.bztmon.com is now a chapter index: 01 The Exploded Cluster
(moved to /cluster) and 02 The Mirror (/mirror), with a forming-chapter ghost
slot. The Mirror ships rev 3 of the dossier - six curated plates fingerprinted
under /assets/, its scroll engine as an external fingerprinted script (CSP
script-src self holds), diagrams as inline SVG, replay panes from real
receipts. Assembler grows a shared document shell + per-page preflight gates;
build.sh inline-script check now covers every page.
