 records desktop/500px computed DOM and screenshots from the PHP service without

+The NPC policy suite and its reference collector can be run independently:
+
+```sh
+PLAYWRIGHT_FRONTEND_PORT=15126 \
+  pnpm --filter @sammo-ts/game-frontend test:e2e:npc-policy
+
+REF_PARITY_USER=refuser1 \

+REF_PARITY_BASE_URL=http://127.0.0.1:3400/sam/ \
+  node tools/frontend-legacy-parity/reference-npc-policy.mjs
+```
+
+The collector writes desktop and 500px screenshots plus computed DOM JSON only
+when `REF_PARITY_ARTIFACT_DIR` is set. It requires an existing reference general
+owned by the supplied account and never accepts a password on the command line.
+
 For a review run that also writes full-page screenshots, create an ignored
 artifact directory and set `FRONTEND_PARITY_ARTIFACT_DIR` before invoking the
 suite. The ordinary CI run does not write screenshots after successful tests.
