## Summary * **What is the goal of this PR?** Update project documentation to match the current master implementation for cache formats, i18n, file transfer/web server workflows, SD-card fonts, and root user-facing docs. * **What changes are included?** Refreshes `book.bin`/`section.bin` docs for v6/v25, updates File Transfer/Calibre/WebDAV/API docs, documents 24 UI languages and JSON language persistence, updates root README/USER_GUIDE cache and network details, and syncs the tracked CLAUDE skill doc cache-version notes. ## Additional Context * Docs-only change. Verified with `git diff --check origin/master..HEAD` and stale-reference greps for old cache versions, removed i18n APIs, old WiFi screen wording, and raw `Serial.printf` examples. No firmware build was run. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

Focus Reading
Focus Reading is a reading aid that bolds the first portion of each word, guiding your eyes to natural fixation points and helping you read faster with less effort. Some readers — particularly those with ADHD — find it helps them stay engaged with the text and reduces mind-wandering. It is inspired by the Bionic Reading technique.
Left: Focus Reading off. Right: Focus Reading on. Both using Literata.
Enabling Focus Reading
- Open Settings > Reader
- Toggle Focus Reading on
Toggling the setting invalidates affected EPUB section caches for the current layout, the same as changing font settings. Sections are rebuilt on demand, then page turns proceed as normal. No changes are made to your EPUB files.
Examples
Focus Reading with Noto Serif font
Focus Reading with Merriweather font
Focus Reading with Atkinson Hyperlegible Next font
Notes
- Focus Reading only applies to regular body text. Already-bold text (headings, emphasis) is left unchanged.
- The setting is per-device, not per-book — it applies to all books while enabled.
