Task 172: Landing Page Redesign — Reading Guide & Navigation Flow

Status: DONE

Goal

Redesign the landing page to help first-time readers understand what the site offers, how to navigate it, and what the key findings are — following Codex's "clearer trust + clearer story" recommendation.

Background

Codex consultation (2026-02-25): "biggest opportunity is not more physics, it's clearer trust + clearer story." The landing page is currently functional but doesn't guide readers or present the narrative arc. A new reader landing on the page doesn't know:

• What order to read reports in
• What the overall findings are ("is the anime accurate?")
• What makes this analysis trustworthy
• How deep they can go

Changes

1. 30-second summary ("この考証の結論") — One paragraph answering "is SOLAR LINE's orbital mechanics accurate?" with key stats
2. Reading guide section ("はじめに読む") — Recommended reading paths for different reader types:

- SF anime fan: Episode reports in order (EP1→EP5)

- Orbital mechanics enthusiast: Ship specs → Cross-episode → Specific transfers

- Quick overview: This page + Cross-episode summary

1. Key findings highlights — 3-4 most interesting/surprising findings with links
2. Prev/next navigation on episode pages — Add episode navigation strip
3. Per-page "3-line conclusion" — Brief summary at top of each episode report

Scope for this task

Focus on items 1-3 (landing page content). Items 4-5 are separate tasks (navigation flow).
