Task 031: Enhanced Index (Top) Page

Status: DONE

Goal

Enhance the top page (index.html) of the published GitHub Pages site with a rich project overview and key findings summary. The current page was just a list of links — visitors need context about what SOLAR LINE is and what the analysis found.

Changes

1. report-types.ts: Added VerdictCounts interface; extended SiteManifest with per-episode summary, verdicts, and site-wide totalVerdicts
2. build.ts: Added countVerdicts() helper; updated buildManifest() to compute verdict statistics from episode data
3. templates.ts: Enhanced renderIndex() with:

- Project introduction (ゆえぴこ, SOLAR LINE, ケストレル, きりたん, route overview)

- Stats section showing episode/transfer counts and verdict breakdown badges

- Episode cards with summaries and per-episode verdict badges

- New CSS classes: .stats-grid, .stat-item, .stat-number, .stat-label, .stat-count, .episode-card, .episode-meta

1. 17 new tests: countVerdicts, buildManifest verdict statistics, renderIndex enhanced content
2. All text in Japanese (日本語)

Test Results

• 670 TS + 52 Rust = 722 total (0 failures)
• Site builds successfully (5 episodes, 24 transfers, 1 summary)

Depends on

• Task 005 (report pipeline) — DONE
• Task 021 (cross-episode consistency) — DONE
