## Summary
* **What is the goal of this PR?**
* Make manual clock sync work even when the device is not already
connected to Wi-Fi, so the user can start the sync flow directly from
settings instead of being blocked by connection state.
* **What changes are included?**
* `ClockSyncActivity` now launches the normal Wi-Fi selection flow
before syncing when the device is offline.
* After Wi-Fi selection succeeds, clock sync resumes automatically and
performs the existing forced NTP sync.
* If clock sync had to bring Wi-Fi up, the activity disconnects and uses
the existing silent restart cleanup path to avoid leaving the device in
a fragmented post-Wi-Fi heap state.
* The completion UI now only advertises Back, matching the updated input
handling.
## Additional Context
* Existing behavior is unchanged when Wi-Fi is already connected: the
activity syncs immediately.
* Cancelling Wi-Fi selection exits the clock sync flow.

## Summary
* **What is the goal of this PR?**
* Fix EPUBs where internal file references are written in URL-style
escaped form, like spaces appearing as `%20`, so the reader can find the
right files instead of treating those references as missing.
* **What changes are included?**
* Added a small shared helper that converts those escaped EPUB-internal
paths back into their normal filenames before we try to look them up.
* Applied that cleanup step across the EPUB parsing flow wherever we
resolve internal references, including cover images, manifest items, TOC
links, spine entries, and inline HTML images.
* Kept the change narrowly focused on EPUB-internal asset resolution
rather than changing broader URL or networking behavior.
## Additional Context
* The user-facing bug here is that some books package their internal
filenames in an escaped form, so a file like `Chapter 1.xhtml` may be
referenced more like `Chapter%201.xhtml`. The reader was treating that
escaped text as the literal filename, which means otherwise-valid books
could lose images, covers, or chapter targets because the lookup no
longer matched the real file inside the EPUB.
* Risk is intentionally low. The helper only rewrites valid `%XX` escape
sequences and leaves malformed input alone, so it should improve
compatibility with escaped filenames without broadening the parser’s
behavior in unrelated cases.
## Local Testing Performed
* This was tested on my device with the user-provided optimized epub
that was not rendering images within the text prior to this fix (cover
image and chapter headers were rendering fine):
[orv_main_baseline.epub.zip](https://github.com/user-attachments/files/28529545/orv_main_baseline.epub.zip)
* This was also tested by the user with a local build and the affected
epub and confirmed to be working
## Steps for Testing
* Try to open the affected epub (linked above) or any epub that has
similar percent-encoding on a build prior to this fix.
* Apply this fix, clear book cache, and re-open the affected book.
* Images should render properly.

## Summary
* **What is the goal of this PR?**
* This PR ports over Crossink's handling of large EPUBs that helps
prevent crashes during open after the book metadata cache is built.
* **What changes are included?**
* Removes the post-indexing ZIP-wide CSS discovery pass that built an
in-memory map of every ZIP entry.
* Reuses `content.opf` parsing to collect declared CSS files without
writing spine entries again.
* Temporarily releases the loaded book metadata cache while rebuilding
CSS for cached books.
* Parses CSS before reloading `book.bin` after a fresh cache build,
leaving more heap available during CSS rule parsing.
## Additional Context
* User reported their EPUB opening fine on Crossink but would crash on
Crosspoint. Verified this claim on my own devices.
* The crash this addresses happened after `book.bin` was successfully
built, when CSS discovery allocated a large `unordered_map` for ~3k EPUB
ZIP entries.
* Tradeoff: CSS files not declared in `content.opf` are no longer
discovered by scanning the full ZIP. This avoids the high-risk memory
allocation but improperly formatted EPUBs (ones that don't declare their
CSS styles in `content.opf` will render without styling and fallback to
inline styles.
* User provided epub that was crashing prior to this change:

## Summary
* **What is the goal of this PR?**
Improve the X3 clock UTC offset picker so it is clearer which part of
the offset will change when the user presses up/down.
* **What changes are included?**
Replaces the single underlined `UTC +/- H:MM` string with separate
editable fields for the sign, hour, and minutes.
The editable fields are spaced out, outlined, and the currently selected
field is highlighted with a light gray background.
## Additional Context
* This is a render-only UI change in `ClockOffsetActivity`; it does not
change how UTC offsets are stored, clamped, saved, or applied.
* The selected field still cycles with Confirm, and up/down still
adjusts the active sign/hour/minute value.

## Summary
### **What is the goal of this PR?**
This fixes an unintended settings side effect when cycling the `Sleep
Screen` option through `Quick Resume`.
Previously, selecting `Sleep Screen = Quick Resume` globally forced
`Quick Resume on Timeout = ON` and left it enabled even after the user
toggled `Sleep Screen` to another option within the same settings
session. Now the auto-enable behavior is scoped to the Settings screen
session:
- If `Quick Resume on Timeout` was already `ON` when entering Settings,
it stays `ON`.
- If it was `OFF`, selecting `Sleep Screen = Quick Resume` temporarily
turns it `ON`.
- If the user then switches away from `Quick Resume`, it turns back
`OFF`.
### **What changes are included?**
- Removes the global logic that permanently forced `Quick Resume on
Timeout` to `ON` whenever `Sleep Screen` was set to `Quick Resume`, even
if it was just due to toggling through the options.
- Adds Settings-screen session tracking so `Quick Resume on Timeout` is
only auto-enabled while the user has `Sleep Screen = Quick Resume`.
- Restores `Quick Resume on Timeout` back to `OFF` when the user
switches away, but only if it was `OFF` when they entered Settings.
- Preserves existing `ON` timeout preferences.
- Same behavior applies to the web settings
## Additional Context
- Tested this on device and via the settings UI

## Summary
**What is the goal of this PR?**
Adds a clearer Quick Resume sleep-screen flow. The previous “Page as
Sleep Screen” behavior is now exposed as a dedicated `Sleep Screen >
Quick Resume `option, with the timeout-only behavior controlled by a
renamed `Quick Resume on Timeout `setting.
**What changes are included?**
- Adds `Quick Resume` as a new `Sleep Screen` option.
- Renames the old `Page as Sleep Screen` setting to `Quick Resume on
Timeout`.
- Changes that setting’s choices from `Never / After Timeout / Always`
to `OFF / ON`.
- Makes `Quick Resume on Timeout = ON` equivalent to the old `After
Timeout` behavior.
- Makes `Sleep Screen > Quick Resume` equivalent to the old `Always`
behavior.
- Automatically forces `Quick Resume on Timeout` to `ON` when `Sleep
Screen` is set to `Quick Resume`.
- Renames internal setting references from `seamlessSleepScreen` to
`quickResumeSleepScreen`.
- Updates translations for the renamed setting label.
**Additional Context**
- This is mostly a settings/labeling restructure around existing
behavior, not a new rendering path.
- The runtime quick-resume behavior still uses the existing saved
framebuffer / last-screen sleep flow.
- Review focus areas:
- Sleep entry behavior from manual sleep vs timeout sleep.
- The automatic dependency where selecting `Sleep Screen > Quick Resume`
sets `Quick Resume on Timeout` to `ON`.

## Summary
**What is the goal of this PR?**
* Provide a better default weight of Bitter font for improved rendering
**What changes are included?**
* Changes the default weight for Bitter font that is defined in the
custom font catalog to medium (500) from regular (400) for improved
rendering on e-ink, especially when font anti-aliasing is turned on
## Additional Context
* Bitter font at regular weight can become washed out when AA is on due
to some of the thinner stems and posts of the font. Bumping the weight
up to medium makes it sturdier and holds up better when AA is turned on.

## Summary
**What is the goal of this PR?**
Restore compatibility with older XTC files that use the legacy 48-byte
header layout, so they open correctly instead of failing
header/page-table validation.
**What changes are included?**
- Updates the XTC parser to accept legacy files where pageTableOffset
starts at 0x30 instead of the newer full header size.
- Avoids treating legacy header bytes as a valid chapterOffset, so older
files are not misclassified as having chapters.
- Switches XTC file size and seek operations to 64-bit-safe wrapper
calls in HalStorage, which matches the XTC format’s 64-bit offset fields
and keeps page/chapter lookups from narrowing offsets.
- Keeps the existing bounds checks and improves related logging when XTC
page loads fail.
## Additional Context
- This is a narrow compatibility fix for XTC handling. The functional
change is in the XTC parser; the HalStorage changes are supporting
wrapper methods needed by that parser update.
- Risk should be low outside XTC reading, since the HAL changes only
expose existing underlying file APIs rather than changing storage
behavior.
