The credibility pass on Hnefatafl, ported to the template: the ops scripts count traffic through one parser, the reports digest is one program, the plaintext-token fallback and its migration are gone, and the stylesheet holds each shared rule once

From the hnefatafl repo's pass of the same day, everything that touched a
kit-shared file. The visitors digest and the nightly rollup share
deploy/traffic.py, installed to /usr/local/lib/<slug>; the rollup writes
the finished-games count it computed behind "and False". pull-reports.sh
and the reports skill both use deploy/report-digest.ts. The seat line
requires its token hash and the start line its rules revision; the
migration for ledgers written before hashing goes with them. The route
table in server/src/index.ts lists every route; Report, ReportLine and
Tally are declared once in view.ts for both sides; exports nobody
imported are exports no more.

In the client: .small, the × that dismisses, and the frame of the
reading pages are in app.css once; the preferences panel shares the
report slip's modal shape; the room store gains seatEmpty and
seatUnheld, and the lobby and the join page read those instead of
three spellings of their own. The room's moved and awaiting fields
stay: the demo board reads them, and simultaneous rounds are the
contract.

The deploy README no longer describes a browser-only game; the visitors
skill no longer names a /play route; the reports skill's replay call
carries the room's options. The Slack channel id is passed in the
environment rather than filled in as a placeholder.
