Typography was in the stylesheet foliate prepends, which the book overrides;
moved to the appended one. The window keydown handler was never bound.
Also: wider reading area, page on a card, arrows moved onto it, spread gutter,
and the sidebar stays open on chapter clicks.
Drops epub.js's 1600-location pre-pass and its localStorage cache: foliate
hands back a CFI and an overall fraction on every relocate, so first open no
longer freezes.
Also fixes resuming (pre-resolves the stored CFI, falling back to the stored
percentage rather than silently resetting to page one), progress saving
(missing Content-Type, and no flush on the way out), and arrow keys inside
the book iframe.
Settings are validated on read, not only on write: several go straight onto
foliate's renderer as custom-element attributes, where a bad value wedges the
layout silently rather than throwing. Unknown keys are stripped and missing
ones filled from the defaults, so settings added later do not invalidate what
a reader already has stored.
The stylesheet is built as foliate's [before, after] pair. The paginator
prepends the first to the section's <head> and appends the second, so the
book's own CSS overrides the first and loses to the second. Typography goes
in the first — a book that styles its own headings still gets to, and font
size lands on <html> without !important so rem/em headings scale rather than
being flattened. Colour goes in the second, because most EPUBs set a body
background and would otherwise leave the page white against a dark UI.
Font choices are reused from the app theme's FONT_STACKS rather than
duplicated, so the reader cannot drift from the rest of the UI.
Rename the ambient declaration to foliate-js.d.ts: as foliate.d.ts beside
foliate.ts, TypeScript takes it for that file's emitted declaration, drops it
from the program, and every $foliate import fails with TS2307.
$foliate is a Vite-only alias, deliberately absent from kit.alias and
tsconfig paths: TypeScript cannot resolve it, so the ambient declaration in
src/lib/reader/foliate.d.ts is the only candidate and svelte-check never
walks the ~11k lines of untyped vendored JS. The generated tsconfig includes
src/**/*.js and checkJs is on, so src/lib/vendor is excluded as well —
`exclude` replaces rather than merges, hence the repeated service-worker
entries.
optimizeDeps.include for construct-style-sheets-polyfill: it sits behind a
dynamic import in fixed-layout.js, so Vite would otherwise discover it
mid-session and force a page reload on the first fixed-layout EPUB.
Verified with a temporary import that the graph resolves: view.js and
paginator.js are emitted as chunks, and the bundled pdf.js is our stub
rather than upstream's bare `import '@pdfjs/pdf.min.mjs'`.
