Lighthouse Static Preview Audit — 2026-06-23

Purpose

This document records the Lighthouse audit result for the public-safe static documentation preview after the Vercel static build, visual layout and SEO metadata improvements.

The purpose is to preserve evidence that the documentation preview is not only deployable, but also passes basic automated checks for accessibility, best practices and SEO in both desktop and mobile-style audits.

Scope

This note applies to the public-safe Vercel static preview:

https://technical-documentation-rho.vercel.app/

The audit covers the static preview layer only.

It does not prove that the repository is a production documentation platform, a full web application or an enterprise content system.

Audit context

The Lighthouse reports were captured after the following improvements:

• static Vercel build path added
• minimal Markdown-to-HTML generator added
• Markdown table rendering improved
• public/static preview boundary clarified
• deployment recovery summary added
• recruiter summary added to the portfolio narrative
• visual layout added to the static preview
• SEO metadata added to the static preview template

The final SEO fix added:

• meta description
• canonical URL
• Open Graph metadata
• Twitter card metadata
• page-specific descriptions for published documentation pages

Final Lighthouse result

The final desktop-style audit result was:

Performance: 1/1
Accessibility: 21/21
Best Practices: 4/4
SEO: 4/4

The final mobile-style audit result was also:

Performance: 1/1
Accessibility: 21/21
Best Practices: 4/4
SEO: 4/4

This means the earlier SEO issue was resolved.

Resolved issue

The earlier Lighthouse result showed:

SEO: 3/4
Document does not have a meta description

After adding the SEO metadata, the final audit showed:

SEO: 4/4
Document has a meta description

What this validates

The audit validates that the static preview has:

• a document title
• a meta description
• crawlable links
• descriptive link text
• sufficient baseline accessibility checks
• valid basic HTML/document structure
• no obvious best-practice failure in the checked categories
• desktop and mobile audit parity for the tested page

The result supports the idea that the public preview is technically clean enough for a portfolio link.

What this does not validate

The audit does not prove:

• production readiness
• enterprise documentation platform maturity
• full manual accessibility compliance
• full security assurance
• full content correctness
• full privacy review of every possible future page

Lighthouse is a useful automated baseline, not a complete governance or accessibility review.

Portfolio value

The audit is useful portfolio evidence because it shows that the documentation work was not treated only as text.

The documentation hub now has:

• deployable static output
• public-safe boundary rules
• visual layout
• SEO metadata
• accessibility-friendly baseline structure
• clean Lighthouse baseline result
• documented recovery and troubleshooting history

This supports the broader portfolio theme:

documented, controlled and reviewable technical delivery

Operational lesson

The main lesson was not simply to make Lighthouse green.

The more important lesson was to solve the right problem at the right layer:

Do not add a heavy framework just because the wrong deployment project expects one.
Fix the deployment boundary and keep the documentation preview as lightweight as the use case allows.

This matches the portfolio principle:

right control, right layer, right weight

Final summary

The technical documentation site now has a working public-safe static preview with clean automated Lighthouse baseline checks across the tested categories.

This makes the documentation hub credible as a portfolio-facing evidence layer while keeping its scope calibrated and lightweight.
