build-standalone-html-report

Build or revise polished standalone single-file HTML research reports, incident reports, post-mortems, architecture comparisons, decision briefs, and evidence summaries with responsive tables, charts, diagrams, lightweight interaction, and iterative preview feedback. Use when Codex must turn research, raw measurements, repository evidence, or incident timelines into a self-contained HTML report; add architecture diagrams or data visualizations; improve an existing report from preview annotations; or validate and publish a standalone report.
