- Resume scroll position only when arriving via 继续阅读 (?resume=1).
Plain chapter-list / drawer clicks now actively scroll to top on mount.
- Progress format extended to {chapter, page, ratio} for within-page
precision; legacy bare-number and {chapter, page} still read correctly.
- Tappable skeleton logo (sunflower outline, spins) while a page loads;
tap force-fetches a fresh signed URL.
- Viewport-priority image loading: second IntersectionObserver at margin 0
marks truly-visible pages, drives <img fetchpriority="high"> and fires
immediate single-page fetches that cut the batch queue.
- Bounded image cache: unmount previous chapter's <img> elements when
currentPage > 5 into the new chapter; placeholders stay for layout.
One AbortController per live chapter; unmount aborts in-flight batches.
- Hashed chapter IDs on the wire via hashids; DB PKs unchanged.
- Origin/Referer allowlist + rate limiting on all /api/* routes via a
withGuards(opts, handler) wrapper (eliminates 6-line boilerplate x5).
- robots.txt allows Googlebot/Bingbot/Slurp/DuckDuckBot/Baiduspider/
YandexBot only; disallows /api/ for all UAs.
- Extract pure helpers for future TDD: lib/scroll-ratio.ts (calcScrollRatio,
scrollOffsetFromRatio), lib/progress.ts (parseProgress + injectable
StorageLike), lib/rate-limit.ts (optional { now, store, ipOf } deps),
lib/api-guards.ts.
- New env keys: HASHIDS_SALT, ALLOWED_ORIGINS (wired into docker-compose).
