The site is built, checked and documented. Here is the outcome.

Deliverable. A single-page explorable retelling of chapter 30 of Snowmoon lives in web/ (Vite, React 19, TypeScript) with the production export committed to dist/. The chapter is retold in original words with short marked quotations, across thirteen beats in three colour phases (night, dawn, day) that brighten as the story moves toward sunrise. The visual direction combines a spacious, system-font, glass-header feel with chunky rounded shapes, bright per-character bot avatars and a striped "tasks-style" reading progress bar.

Interactive pieces

• Four replayable group chats (play, next, show all, reset).
• The pattern lab: a seeded toy of the black-box attack. Tweak a printed pattern, keep what slows detection, and toggle "our own model's hints" to see why Lui's surrogate shortcut converges in about 30 tweaks where blind search needs hundreds.
• A casualty-ratio chart that shows only figures the chapter states, with hatched bars for unstated stages.
• A before/after schematic battle map, an original drawing, switched by a radio segmented control.
• A filterable cast, a native-details glossary, and a "Why it matters" section tying the tricks to real adversarial-patch research.

Checks that ran

• Typecheck passes, 14 tests pass, production build succeeds. Asset URLs are relative.
• Browser inspection of the export at 1280, 375 and 320 px: no overflow, no console errors, four requests all 200. Skip link, focus rings, keyboard tabs, reduced-motion emulation and every primary interaction were exercised.
• Contrast computed for 38 token pairs (lowest text pair 5.17:1). The map's two-category palette passes the palette validator.

Review findings fixed (recorded in artifacts/validation.md): invisible ratio bars in the day theme, a misleading "+99 %" starting gain in the lab, a hill-climb too flat to reach the "dog" verdict, the missing phase colour progression, a light-on-light map label, a marker collision, a stuck nav highlight, and stale phase captions.

Limitations. No screen-reader session, native zoom, forced-colors render or physical device. Screenshots were inspected inline but could not be written into the repository because the browser tool's output directory is not visible to the shell. The pnpm store on this box is read-only, so npm produced the lockfile. Publishing beyond the committed dist/ was not possible from the sandbox; the README covers Pages, IPFS/ENS and generic static hosts. web/node_modules was removed and is git-ignored, and the tree is under 1 MB.

Docs: README.md (install, preview, rebuild, publish, validation results), DESIGN.md (tokens, typography, layout, components, do's and don'ts) and artifacts/validation.md (coverage, findings, verification, completion).
