Remove local Codex home paths from QA doc

This new QA note commits machine-local /Users/timmy/.codex/... artifact paths, which are not usable by anyone else and violate the repository guideline in AGENTS.md to not commit “temporary Codex homes”. Replace these with repo-relative artifacts, durable links, or a summary that does not expose local Codex workspace paths.

Stack the footer before tablet widths overflow

At widths just above the 840px mobile breakpoint, this desktop footer grid still requires the 230px and 380px tracks plus two 28px gaps and an unwrapped navigation column; after the footer margins and padding, an 841px viewport leaves only about 757px of content width, so the nav cannot fit and the page can gain horizontal scroll until the mobile rule starts. Move the footer stacking/wrapping breakpoint up or allow the navigation column to wrap/shrink safely.
