Task 027: Report Quality Review (Round 2) — Codex Consultation

Status: DONE

Objective

Periodic report quality review as directed by CLAUDE.md. Used Codex consultation to review reports for readability, accuracy, and completeness. Fixed all high-priority issues found.

Codex Review Findings (6 issues identified, ordered by severity)

1. Transfer explanations rendered as raw text — markdown not converted to HTML
2. SVG marker ID collisions — same orbit pair transfers share arrowhead IDs
3. EP05 provisional status insufficient — only in intro, not on cards
4. Comparison table alignment — .numeric class applied to text cells
5. No prev/next episode navigation — requires backtracking from deep pages
6. Mobile layout risk — calculator controls compress on narrow screens

Changes Made

• [x] Markdown in transfer explanations: Now renders bold, lists, code via markdownToHtml()
• [x] Markdown in episode/summary summaries: Same treatment
• [x] SVG marker IDs unique: Arrow IDs now include transfer index (-0, -1, etc.)
• [x] Animation pathIds match: Updated animation JSON pathId generation to use same indexed format
• [x] Smart numeric detection: Comparison table cells only get .numeric class for actual numbers/measurements
• [x] EP05 provisional badge: 暫定分析 badge (verdict-indeterminate style) on episode title when summary contains 暫定
• [x] Prev/next episode navigation: Bottom nav bar with prev/next episode links + top link
• [x] Mobile responsive: Added @media (max-width: 600px) breakpoint for calculator and table layouts
• [x] 13 new tests: Covers all changes (markdown in explanations, prev/next nav, provisional badge, numeric detection, marker IDs)
• [x] All 493 tests pass (was 480), Rust 52 pass
