feat(journal): W1 「我的手帐」 — /me/journal page for logged-in users

[emptylower]

Summary

W1 of the 6-week MVP: new private route /me/journal that renders a logged-in user's personal "pilgrimage handbook" — cover + 7 data-viz sections + 4 explore cards + LBS floating button, in a paper-journal visual style.

• New lib/journal/ domain following the existing 3-layer pattern (api factory → handler → repo Prisma + Memory double)
• 6 reusable visual primitives (PaperCard, RedSeal, WashiTape, InkDivider, StitchedBorder, PageFoldCorner) under app/(authed)/me/journal/primitives/
• 10 section components composed into a server-rendered page with auth gate
• 43 unit tests across vitest node + jsdom projects, all green

Out of scope (W1 NOT-doing list)

Per the W1 plan and product charter §9, these are explicitly deferred:

• Default post-login route is unchanged (/me/journal is a new route, not a redirect target — W4 handles route migration)
• recentNotes always returns [] (notes write/read system is W2+)
• travelModeBreakdown is a static stub (real per-user calculation is W2+)
• Favorite tables are NOT merged (W2)
• No journal public/private toggle (W5/W6)

Charter compliance (docs/product-charter.md)

• §3 五条设计原则: respected
• §4 词汇表: page text uses only allowed vocabulary (no "朱印 / 誊抄 / 想去笺 / 路书 / 番剧")
• §5 IA: 手帐 is the destination, not a Nav tab
• §8 视觉系统: paper / 朱印 / washi / 缝纫边 all present via primitives
• §10 反 Feature: LBS in floating button (not Nav), no 作品 Tab, no 手帐 Tab

One plan deviation worth flagging

Task 4's Prisma repo uses state: 'checked_in' instead of the plan's 'visited'. The valid enum in lib/userPointState/repo.ts is 'want_to_go' | 'planned' | 'checked_in'; without the correction, every user's check-in count would have been 0 in production.

Follow-ups for W2 (non-blocking)

• listCheckins has no take limit; heavy users force large fetches + in-memory haversine on every page hit.
• countDistinctWorksVisited uses distinct: ['pointId'] + JS Set; a groupBy({ by: ['bangumiId'] }) would be cheaper.
• unlockedAt = now is computed at view time; AchievementWall tooltip will show "unlocked today" for all unlocked badges until W2 introduces persistent unlock timestamps.

Test plan

• npx vitest run tests/journal/ → 43 passed (21 node + 22 jsdom)
• npx tsc -p tsconfig.app.json --noEmit → no new journal type errors
• Manual QA on a temp Worker preview URL: unauth redirect, new-user empty render, data-rich user render, charter §10 anti-feature check, visual match against docs/wireframes/owner-journal-target.png
