Promote /tables, /excel-query, /query-tool, /mid-section-defect from deferred to full shell-governed in-scope routes with canonical redirects, content contracts, governance artifacts, and updated CI gates. Unify all page header gradients to #667eea → #764ba2 and h1 font-size to 24px for visual consistency across all dashboard pages. Remove Native Route-View dev annotations from job-query, excel-query, and query-tool headers. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
