Drops the legacy course-1 template, the two python assemblers the node
assembler replaced, and the unversioned scene manifest left over from the
manifest-<type> split - none referenced by build.sh, the assembler or the
README, and none produce build output. The v2 pages stay: the README lists
them as parked. Also converts typographic dashes to ASCII in build.sh and the
two nginx configs, and corrects an assembler comment that still pointed at the
removed python build.
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.
