Task 010: Localize Reports to Japanese

Status: DONE

Convert all GitHub Pages report templates and existing report data to Japanese (日本語).

Depends on

Scope

1. Update ts/src/templates.ts — all UI text, headings, labels in Japanese
2. Update reports/data/episodes/ep01.json — analysis text, findings, assumptions in Japanese
3. Verify build output renders correctly with Japanese text
4. Future reports (ep02+) should be written in Japanese from the start
