Triage community PR #40 (Diffwatch visual regression capture)

Community PR from pastarita open since 2026-03-17 (78 days). Status: Vercel check FAILURE due to team authorization required. No reviews. Diagnosis: Vercel auth blocker (community contributor cannot authorize Vercel for TextureHQ team). Recommended action: Either (a) manually trigger Vercel deploy via branch fetch + force-push if work looks promising, OR (b) ask Victor if Diffwatch aligns with CommonGrid roadmap before investing review time.
