lib/font-fingerprint.mjs replaces the three-number fingerprint with
size-invariant shape features (x-height ratio, stroke contrast, stem width,
run-length quantiles, roundness, serif signal, width spread) and a
noise-normalized distance; family recall on a held-out self-test rose from
13% to 72% top-5. data/font-index.json carries the whole Google Fonts
catalog (3,092 faces at two cap sizes, 707 KB); font-match --rank fingerprints
the comp crop, takes the 25 nearest faces from the index (plus the model's
own names), renders them at the comp's cap height, ranks by the same
distance, and prints a proof sheet and the CSS to use. scripts/build-font-
index.mjs rebuilds the index at release time.

new-work.md section 6 becomes the spec / plates / hero / sections / motion /
responsive phase list, each closed by build-phase.mjs advance; the
reproduction and hero-checkpoint prose that asked the model to compare
from memory is gone. visualize.md's inventory, medium gate, and produce
sections collapse into the spec and plate mechanism. The finish reviewer
takes the state file and comp-diff reports as inputs and starts its
fidelity matrix from the measured verdicts. docs/COMP-FIDELITY.md records
the design.
