[docs] Add the Reo.dev beacon to the documentation site

[NiveditJain]

Adds the Reo.dev tracking beacon to the Mintlify docs. Also un-reds the Supply Chain gate, which went red on this branch without it changing a dependency — details in the second half.

The install

Mintlify includes any .js in the content directory on every page, once per full page load, after the page becomes interactive — there is no head-injection key in docs.json. So a root file is the entire install, and it is the form Reo's own Mintlify guide prescribes. docs/stars.js is already here on the same mechanism.

The loader is kept byte-for-byte as Reo issues it, minified line and all, so it stays diffable against the vendor snippet without reading past the formatting.

Verified end-to-end

Against mintlify dev in the Dockerfile.docs container, the snippet is inlined on /, /reference/overview, /zh/start/quickstart and /ja — so it covers the generated locales too, with no per-language file.

Why there is a test for a third-party snippet

Analytics is the archetype of code that fails silently. The docs render identically whether the beacon loaded, loaded under someone else's client ID, or never ran — the only symptom is a dashboard that stays empty for weeks, and a quiet week looks the same as a broken install.

__tests__/docs/reo.test.ts drives the script the way a browser does — eval it into a jsdom document, catch the <script> it appends, fire its onload against a stubbed Reo — and pins the three things that decide whether anything gets reported: the file is where Mintlify looks, the loader points at Reo's CDN, and the client ID in the URL is the same one handed to Reo.init. The snippet spells that ID twice; a mismatched pair still loads a working script, it just reports to nobody. Same shape as stars.test.ts, for the same reason.

The sharp bump, which is not this feature

OSV-Scanner failed on the first push, on sharp 0.35.0 — GHSA-rgj7-g3m4-5g8c, CVSS 8.9, two Critical libheif RCEs inherited through libvips and reachable when processing untrusted input. Nothing on this branch touches a lockfile. The advisory published 2026-09-08 21:25 UTC, between main's green Supply Chain run at 14:18 and its red one at 04:31 the next morning (run 34311274320 fails on the same single line), so it turned every open branch red at once — the same surface-late shape CHANGELOG.md already records for browserslist, chromadb and nltk. Per this repo's rule that CI is never left red, it is fixed here rather than filed.

It stays an override rather than becoming a direct dependency, because sharp is still only an optional dependency of next. What changed since #591 first pinned it is the direction of the constraint: that pin existed because next asked for ^0.34.5, a range excluding the then-fixed 0.35.0 — next 16.3.4 now asks for ^0.35.4, so the pin had inverted into the thing holding the tree below what its dependent wants. osv-scanner.toml gains no entry: a fixed version exists, which is exactly the case the allow-list is not for.

Verified past a green lockfile the same way #591 did:

• sharp 0.35.4 loads against libvips 8.18.6 (@img/sharp-libvips-* 1.3.0 → 1.3.3) and round-trips a PNG encode
• CI's scanner image (ghcr.io/google/osv-scanner-action:v2.5.0, same four lockfiles, same config) on the updated lockfile: No issues found, exit 0, with only the pre-existing dated chromadb/nltk filters applied

Checks

• bun run test:run — 257 files, 4868 passed (before and after the bump)
• bun run build — clean
• bunx tsc --noEmit — clean
• bun run lint — 0 errors (5 pre-existing warnings)
• CHANGELOG.md updated under ## 1.0.4-beta.0 → ### Docs and ### Dependencies

Summary

No actionable correctness, security, compatibility, data-safety, or operability issues found. The beacon follows the existing root-level docs script integration pattern, and the sharp override and lockfile agree with Next’s optional dependency range.

Changes

• Added a documentation-wide Reo analytics loader and DOM-level regression coverage.
• Updated the sharp override from 0.35.0 to 0.35.4 and refreshed its Bun lockfile entries.
• Documented both changes in the changelog.

Validation

• Passed docker run --rm --network=none … bun -e '<evaluate docs/reo.js with stubbed document and Reo>' — Network-isolated smoke check confirmed the loader appends exactly one async Reo CDN script and initializes with the matching client ID after onload. (0s)

Findings

None.

None.

📝 Walkthrough

Walkthrough

The documentation site now loads a Reo.dev beacon that matches the Mintlify loader. Tests validate loading, initialization, async behavior, client ID usage, and single injection. The sharp override now uses version 0.35.4.

Changes

Reo Beacon Installation

Layer / File(s)	Summary
Beacon loading and validation docs/reo.js, __tests__/docs/reo.test.ts, CHANGELOG.md	The beacon injects an async Reo CDN script and calls Reo.init after loading. Tests validate the client ID, loader text, async flag, single injection, and file placement.

Sharp Override Update

Layer / File(s)	Summary
Sharp override and changelog package.json, CHANGELOG.md	The sharp override changes from 0.35.0 to 0.35.4. The changelog records the update.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to cf59d

This change adds a documentation tracking beacon and updates the sharp override. The remaining risk is limited to the new test's repository-required placement, which could affect expected test discovery or maintenance conventions.
