Summary

Address the Nuxt audit while retaining static generation and the existing app structure.

• Prevent draft publication; centralize publication policy, shared article types, production origin, and public routes.
• Fix article 404s, scroll restoration/anchors, static legacy redirects, robots, sitemap, and XML feed output.
• Generate responsive thumbnails, optimize the noise texture, keep SSR images visible, and restrict speculative prefetching to interaction.
• Clean up audio/MIDI resources and matrix listeners; improve experiment controls and accessibility.
• Simplify the 404 to 404 / Page not found, without a card, shadow, or return-home link.
• Add PR/main CI validation, production/static browser regression coverage, and validated-artifact deployment.

Validation

• pnpm typecheck
• pnpm test — 5 passing
• pnpm build
• pnpm test:e2e --project=server — 12 passing
• pnpm generate
• pnpm test:output — 4 passing
• pnpm test:e2e --project=static — 9 passing
• Frozen-lockfile compatibility and diff checks

Performance

Three post-change cold-cache mobile lab runs: home/experiments total transfer is roughly 75% lower; image transfer is 92–94% lower. Compiled JavaScript remains about 109 kB gzip, below the historical 116 kB review budget. Timing comparisons against the single pre-change run are directional, not field Core Web Vitals.

Audio/MIDI tests use mocked devices; physical hardware was not tested. Previously published drafts remain public until deployment, and this change does not erase prior history.
