[Draft — switch on later] Restore field velocity on detail pages

[lksbrssr]

Draft switch-on PR — merge only when the detail pages are ready

Hiding PR #154 is merged. This draft has been rebased onto the actual post-merge main and now targets main. Only the approved restoration commit was replayed after the squash merge, preserving the intended four-file restoration diff. It remains a draft for a later explicit switch-on decision; no merge or launch is authorized.

Restores the original field-velocity panel on all four public focus-area detail pages, including chart/inflection interactions and the existing cross-field overview, methodology and toolkit links. Restores the original positive route-mounting tests and removes the incompatible launch-hold assertions.

The complete src tree is byte-for-byte identical to main immediately after PR153, cea75883bbed07cb751a3bc17c5b677cfa587b74. The full repository tree also matches the previously prepared restore head deda95968c0bf0d764bbcb78e54d7b4990882f5d. No metrics, styling, API/data, other sites, navigation, cryptic cross-field route or noindex metadata changed. It does not promote /impact/; older draft #105 remains a separate decision. As before the hide, detail-page links would make the cryptic overview discoverable from those pages again.

Hosted preview

Vercel SUCCESS on the newly verified rebased head a5fcf2bdebc9ef136ae7286d97fd615ad7be12f1, based on e1923a6e693eb3b45fcbaaa0efea196d279ca577. The exact commit's immutable deployment was exercised, not merely the older branch deployment.

Restored Neurotech detail · Unchanged cross-field preview. Both branch-alias routes were also read back successfully.

Verification of the rebased head

• Fresh pnpm 10 frozen install, 75 tests, TypeScript and production build pass sequentially at a5fcf2bdebc9ef136ae7286d97fd615ad7be12f1.
• Independent isolated code review passes. Exact four-file delta, unchanged full repository tree versus the prior restore, pre-hide src equality, and clean worktree verified deterministically.
• 24 fresh hosted browser cases at 1440, 390 and 320px: all four restored detail routes and all four selected cross-field tabs. Detail chart fragments open; preview chart URLs, data/source flips, Escape dismissal, five overview cards and the three existing detail discovery links remain functional.
• 18 hosted HTTP boundary checks pass: detail mounts, exact preview/noindex, navigation/index discovery exclusions, all four JSON feeds with CORS, unknown-area 404 and still-unpublished /impact/ and /field-velocity/ routes.
• Original local evidence and unchanged limitations. Original local application QA and screenshots were captured at e426c490736f055794428e39733b160c31de295b; their source tree remains identical to the rebased head. Existing provider fallback/cache warnings and baseline narrow-width overflow are unchanged; no new data freshness is claimed.

Screenshots

Original local production-build captures of the exact restored pre-hide application tree at e426c490736f055794428e39733b160c31de295b, not new hosted captures or a production launch. Image bytes were reverified against the repository; these captions intentionally preserve their original provenance.
