rdmsm4x-changelog-20260922-2010-amagansett-fabric-studies

Built three near-white woven-fabric directory UI studies and a navy dark mode for amagansett.app.

Scope: rdmsm4x; isolated branch codex/amagansett-fabric-studies-20260922. Base d2eadf216a3ddfa7c6575214c51ba230f216a215. No production integration or deployment; AK and Forst untouched. Files: design/fabric-studies/{index.html,style.css,app.js,weave.svg,compare.html,DESIGN.md,verify.mjs,capture-board.mjs,verification.json,accessibility.json,-desktop.png,-mobile.png,navy-mobile-map.png,light-comparison.png}; SESSION-STATE.md appended in isolated worktree. Artifact root: /Users/richh/dev/_handoff/codex-out/amagansett-fabric-studies-20260922 Review: http://rdmsm4x.local:4873/compare.html Validation: node design/fabric-studies/verify.mjs — 19 checks pass; desktop 1440px and mobile 390px; zero browser errors. node design/fabric-studies/capture-board.mjs — no WCAG2 A/AA axe violations in light or dark; screenshots visually inspected. HTTP review URL returns 200. Reproduce server: python3 -m http.server 4873 --bind 0.0.0.0 --directory design/fabric-studies Decision: recommend Porcelain #FAF9F4 as the nearly-white starting point. Chalk #F6F3EB and Oyster #F4F5F1 remain available; navy #102638. Fine/pronounced weave and System appearance controls available. All listing content and map geometry are illustrative. Rollback: standalone additive mockups; no live files replaced. Stop only the owned port-4873 preview server to stop serving. Retain worktree and screenshots for review; no backup needed for additive files. Pending design choice: user feedback on light palette and weave strength before major implementation. No technical owner action required.
