Chapter list:
- Book page now shows the first 50 chapters only; a 'Load more' button
(HTMX, GET /books/{slug}/chapters-page?page=N) appends the next page
without a full navigation, replacing itself with the next load-more
button or disappearing when all chapters are loaded.
Reading progress:
- Visiting a chapter saves {slug: chapterN} to localStorage under
'reading_progress'.
- The book page reads that key on load and, if a saved chapter exists,
highlights the saved chapter row with an amber dot and shows a
'Resume — Chapter N' button that navigates directly to it.
- Progress dots are also re-applied after each Load More via
hx-on::after-request.
