cursor[bot]: an expression mixing loop bindings with outer free names
(fmt(r.label) where fmt lives in the route script) was left verbatim, so
the detached preview referenced an undeclared identifier and failed at
mount, past the compile gate, because globals make it legal to the
compiler. Such expressions now mark the analysis unsupported and the
session takes source-preview mode. A globals allowlist makes Math/JSON
and friends count as neither free nor bound, which also fixes a latent
bug where a pure-global expression minted a nonsense prop.
Won't-fix on the same pass: the live-setup.md filename cross-reference
matches the repo's established reference-link convention.
